Thank you very much….my vaillant boiler wasn’t on for over 1 year as I’ve been away and when I come back didn’t work…..I’ve seen your video and I have done exactly the same and now the boiler is working fine Thousand thanks for this God bless you
Thank you so much for this! My boiler was disconnected at work for an extension build and when I recommissioned it I had fault F75. I was getting ready to change the sensor and even the pump but after seeing your video I did what you said and the pump came right back to life. Cheers
Firstly you should mention that you should turn the power off to the boiler in case it kicks in whilst you are fiddling about with that small screwdriver in the pump. Secondly on the pump label in the 5 o clock position is an arrow - that is the direction of the pump - if you start turning it like you did in the opposite direction there is a good chance you will damage the pump vanes causing loss of pump pressure and having bits in the pump cylinder that will damage other vanes.
Firstly, he and you should mention, there is no need to open the bleeder completely. If the boiler is switched on and running, a simple half-turn would show you if the water pump is working if water and or boiling water gushes out! Then you know its working.
I can see my pump is spinning when I remove that threaded plug but the radiators are still cool to the touch. Could the impeller be broken? Is there any way short of draining the system and removing those four hex bolts and taking off the pump to visually inspect the impeller?
This is amazing, I was desperate and couldn't get hold of a gas engineer.. I wacked the pump hard several times and wow! the pump stated vibrating, and the boiler came on.. should I get a new pump?
Thanks for video. very clear. ok removed the front nut, turned the inside screw- action seems fine...so put it all back together...turned to heat mode...the pump casing itself is getting very hot, is this normal? I can feel vibration and assume water passing through...I have hot water fine...but I only have two large cast radiators on this system, I dont believe they have water in them...as bleed valve produce nothing, but both cold as stone...even though boiler has kicked in, pressure at 1.6...any advice?if I open the feed tap the pressure goes up but not going to the rads.? TIA combination boiler.
Hi I’ve taken the lock off but water continuously pours out of the pump and is very hot, the internal part turns freely but when boiler is running the pump makes no noise. Can you offer advice?
Hi my pump has a lot of water coming out nonstop from bleed valve and it blows fuse in pcb when heating is on but works ok on just hot water do i need new pump?
Hi Peter Sounds like you need to call in a plumber. If you have gravity primaries without the need for pump this would explain why boiler works ok on hot water only
when I run the bath, then after a minute or so the pump produces a clear whirring sound for 10-15 seconds before settling down. what could be causing this? is there an easy check/fix ?
probably a build up of limescale on the pump impeller, needs dismantling and removal of scale. You also may need to top up the Fernox or other brand inhibitor in the central heating system to aid lubrication of this pump
This trick got the pump/boiler working last week, but this week the pump seems to be overheating again. Is there anything else to do to tune up the pump?
I’ve taken the locking but off but the water just constantly runs out when I do this. On your video you only have a small amount of water come out. Can you help?
Hi Jonnie every time I switch the hot water switch on it trips the electrics out. Plus when I’ve also undone the plug on the pump loads of water comes out could this be the problem
I can feel my pump vibrating and its very warm, even hot to the touch. I haven't unscrewed the large screw yet which ill do tomorrow and also unplug from the electrical socket. Is the pump suppose to be hot?
Hi Bradley No need to turn system off before you remove screw. After you have removed the large screw use a small electrical screwdriver to insert into shaft. If the pump is running you will feel it vibrating against the pump impeller as it spins so all good with pump. If the pump is stuck you will feel no vibration. You will then need to turn the impeller with a small slotted screwdriver to free off. When impeller is free the screwdriver will vibrate and pump will start to spin. Remove screwdriver. If then pump is badly stuck you may have to push hard on screwdriver to free off. Sometimes tapping gently with a hammer before you remove screw works so try this first. Hope this helps and all goes well
Something is amiss here and impellor seems to be letting by. This can be because pump is working fine and not stuck? Shut system off and allow to cool. Check system pressure is no more than 1 bar when cold if sealed system(Combi boiler). Remove screw and check if impeller turns. Small amounts of water are normal. If problem persists and you cant free off pump and you have loads of water coming out then you will need to call a plumber to resolve. @@bradjammin
This video shouldn’t be alowed and nobody should be removing the front boiler case if you are not gas safe registered. The boiler case is an important part of the combustion process and the seal around it must be re fitted correctly otherwise it could have deadly consequences
@@m1geo I know it’s only a water pump he’s working on but how did he access it ?! Bottom line is unless your gas safe you won’t understand how important it is that the case is installed correctly!
@@bobbysuk In most combi systems these pumps are not even inside the boiler. I have a Gledhill Boilermate and there is no gas connection. Perhaps the presenter should have mentioned this but there are circumstances where you are not going to be going anywhere near gas.
Just waited 5 freezing days for the Ideal engineer to fix our boiler which was one year old and still under. warranty. He did exaclly you did!

Thousand thanks for this
God bless you
Fantastic!
A million thanks for this video. On the coldest night of the year In Scotland so far, this saved the day. And the emergency plumber's bill.

Fixed my frozen pump! Made my day, thank you!
Hit the pump with a hammer and bingo working again thank you spot on.
This video was my salvation. Better than the engineer who came to my house, it was me thanks to this simple demonstration of professionalism. 🙏🏾

Thank you for perfect advice!!! You saved my day!!! Thank you!
Pump error code 281 I'm getting hot water but no radiators coming on. Did your hot water work before u did this pump fix?
ALL NEW PUMPS LOOK HARDER TO CHECK , HOW DO I CHECK IF THE TURBINE FROZEN
I can see my pump is spinning when I remove that threaded plug but the radiators are still cool to the touch. Could the impeller be broken? Is there any way short of draining the system and removing those four hex bolts and taking off the pump to visually inspect the impeller?
Super ,Thank you very much.
This is amazing, I was desperate and couldn't get hold of a gas engineer.. I wacked the pump hard several times and wow! the pump stated vibrating, and the boiler came on.. should I get a new pump?
Yes, it stopped for a reason. Check the windings, it is probably old. Replace it
Thank you very much! I fixed the heating pump on your advice, thank you!
You have to ensure the heating is off before removing the screw?
There is electronic device on the pump (wilo) i dont know how to remove it
You want to make sure the pump is isolated before you take that screw out .
Please clarify this bit as the tool landed and blocked the word out "if you give it a sharp tap its (what?) the pump off"
Thanks for video. very clear. ok removed the front nut, turned the inside screw- action seems fine...so put it all back together...turned to heat mode...the pump casing itself is getting very hot, is this normal?

TIA combination boiler.
Hi I’ve taken the lock off but water continuously pours out of the pump and is very hot, the internal part turns freely but when boiler is running the pump makes no noise. Can you offer advice?
When you remove the center screw should this device be plugged in or not? Thanks!
yes it should always be turned off before attempting this
Yes you should point our electric to the boiler needs to be (switched off) before doing this.
Thank you so much..sattle my problem
You are most welcome
Where do you find this pump?
I have an ideal logic combi boiler, but cannot find this part.
Do you need to switch off power off to do that
screw is stuck, any tips on how to loosen screw?
Do you need to turn the water off
Or heating system
Further to this the downstairs radiators come on for a short period before going off but the hot water and upstairs radiators work as normal
Same as me what's solution!
Hi.. My pump is seized ..IV brought a new head.. is that a simple fix or replacement if I did it myself?.
Hi did you do it yourself in the end ?
If the pump does not work will you have only hot water or nothing at all (no heat, no hot water) ?
thx our heating wasent working your banging the pump has it working thx agen.
Thanks mate
Done that and the pump moves freely.
Still got 1/3 of the rads that are luke warm and the rest cold.
What would be the next to check ?
check system pressure if sealed system, should be 1 bar minimum, check rads for air, if still no joy you will need to call in a plumber
Hi my pump has a lot of water coming out nonstop from bleed valve and it blows fuse in pcb when heating is on but works ok on just hot water do i need new pump?
Hi Peter

hello . do we have to decreese boiler pressure to 0 while this operation ? thanks
You can do, but remember to increase pressure to 1 bar before you check pump is working
@@goodhomehacks9780 no please look at the 1:13 . pressure must be zero at this instant ???

I’ve taken the locking but off but the water just constantly runs out when I do this. On your video you only have a small amount of water come out. Can you help?
If it sprays water after undoing the plug that means the pump isn't working well and it needs to be changed soon.
Hi, was this the case as mine is doing the same?
Bad advice, NEVER bang a pump or anything, do NOT remove👎 the VENTING screw while full of water, that's dangerous water damage PCB.
Hi Jonnie every time I switch the hot water switch on it trips the electrics out. Plus when I’ve also undone the plug on the pump loads of water comes out could this be the problem
My on spins but doesn't work
"Check heating pump"? There's two pumps... pump one is oil pump and pump two is water pump. Your video refers to a water pump.
I can feel my pump vibrating and its very warm, even hot to the touch. I haven't unscrewed the large screw yet which ill do tomorrow and also unplug from the electrical socket.
Is the pump suppose to be hot?
well it is pumping hot water, so...
Are you turning off the system before you remove the screw?
Hi Bradley
No need to turn system off before you remove screw.
After you have removed the large screw use a small electrical screwdriver to insert into shaft.
If the pump is running you will feel it vibrating against the pump impeller as it spins so all good with pump.

GoodHomeHacks no problem. Doing this at present but there is STACKS of water coming from the pump as I open it

Oh, behave mate. Its a waterpump! 🙄

Bottom line is unless your gas safe you won’t understand how important it is that the case is installed correctly!
