[jimnastick]

i have a baxi 105e (not instant) and having problem with hw ch is fine when i call for hw the boiler fires up and the temperature lights start rising but stop once it get to 60c. the boiler then turns off and then restarts but just staying at 60c. can anyone point me in the right direction and is it a job i could possibly do myself or not

Are you actually getting any hot water out of the taps?

 

[jimnastick]

hi there thanks for the reply
yes i get hot water out of the taps and just enough for a shower but when it comes to doing the pots its not so great

Possibly blocked plate heat exchanger.

The Chap who changed the PCB didnt set up the dial on the front of the boiler to the correct position on the potentiometer on the board

so the boiler thinks you only want the water to heat up to 60 degs

get him back and tell him to set both potentiaometers (CH and HW) to max and the dials on the front to max and re install the PCB.

Job done

well finally got engineer round (he lost my details) passed on the info you gave me he has now fixed the problem but at first he just moved the potentiameters and it didnt work(started scratching his head) i passed on the info about setting the dials to the potentiameters he tried and it worked a treat i would like to say a big thanks because without your info i think he would struggled to fix it
once again many thanks corgiman
