Bosch Dishwasher: tap (faucet) and sun symbol flashing

After a leaky pump sump (E15) I installed the silicone seal (not replaced) and then the following error still came: the tap and rinse aid flashes.
Obviously, this is not a permanent error. After a few minutes (approx. 1:25 - it stopped) it makes "clack" and the planned flushing time (here: 2:30) appears again - as usual ... Hope this helps. The device is from 2012.
