Thanks for posting Jay. I assume when the boiler was fitted it was sized for any future expansion. Subsequently it was left being too much for the current demand, hence your visit realised it was wasting energy for the here and now and duly rectified. Surly this should of been part of the commissioning process.
Interesting.( regarding working slower).. is this the same for Flexicom' s CX & SX???. It's just that I work for a local authority and due to agreement with manufacturers we fit Worcester 30i erp boilers in 1, 2 or 3 bedroom flats with 1 bathroom and a max of 7 radiators... It's also current regulations (as far as I'm aware) that Part L is required so as with CCN1 and Cenwat 1you need all 3 or else you shouldn't be specifying appliances..
These sensors are a good design and work perfect if the system is clean but can become blocked very easy , the problem is that you get guys that just turn up and change them without checking what caused it to fail and that's usually dirty system water or a lazy pump , if on occasions you turn up to a job and don't have a spare there is a way to bridge them out temp until a replacement is fitted.....👍
Excellent explanation. Been getting this fault for years now. Thank you.
Always a DM away if u need advice or support, view our website for free training material, thanks for the feedback and merry xmas
Never without one in the bag, top design on the early models 👌
Best boilers, best service best interface
Superb video. I have this issue and waiting on our engineer to attend. First fault since it was fitted in 2009.
They r great boilers
Does the pump pressure sensor also send the system pressure to the Pcb and the pressure display ?
The pump increases the pressure which activates the next sequence

Genuinely think most installers don’t calculate heat loss, also if u don’t range rate Vaillant’s they response slower

@@Carl-re6zb all boilers, if u don’t the boilers wastes time calculating the flow return temperatures etc

And how is, for to this? bridge with resistor?
Vaillants have an internal bypass, so shouldn need another one?
System boilers need another one
@@warriorsofwarmth Please can you tell me why that is?
External bypass helps increase flow rates and cool the hex down, also on bigger systems DT maybe higher so it prevents thermal shock
@@warriorsofwarmth Ok thanks!
Hello .What if may boiler indicates 0 presure without showing any error . Tried to top it up and safety valve lifts. can it be pressure sensor?
Needs pressure, error would indicate if boiler doesn’t sense increase
great video
I really appreciate your positive feedback
Thanks
Exellent
Thanks dude
