Baxi Solo 3PFL 60 lock out

[Pooly89]

Hi guys,

I have been called out to a baxi solo 3pfl 60 that I intially had to change the fan on. about 2 weeks later I had a phone call from my mate(the spark) who said that the boiler had stop working, overheat light was on and he had reset it and it was fine. about 3days later the same again so i went out and did a load of testing pump-ok, overheat stat-ok, thermostat-ok. then reset it myself, set the potentiometer to MAX and it got up to temp and shut down and I watched it do this for a while no sign of overheat. I tried to call baxi but as usual only open till 6pm. I have a hunch as it's been so intermittent and feels like its not actually overheating that it maybe the PCB? any one else had this problem or can shed some light on it?

cheers

hi, you need to join the gas safe only forum and ask your gas related questions there. Please contact either gasman or redsaw with your gas safe details.

im assuming there is no circulation problems? struggling to remove heat when trv's are shutting down?

Hi how do I get in contact with gasman or redsaw to give them my gas safe details?

No doesn't appear to be any problem with circulation.

No doesn't appear to be any problem with circulation.

Just send either or both a private message.

Hi Guys this heating system is really starting to get on my nerves. I noticed that the pump wasn't going into over run after the system had reached temp so I checked with baxi they said the overun is on the board so replaced the board a few days ago.

The customer has now called to say that her heating has gone off again and didnt sound impressed obviously started making me look like a a**hole. Ive check differential temps at the boiler it stays at 15deg diff at normal setting and at max so tells me there cant be anything wrong with circulation plus pump seems to be running ok. I have watched it reach temp and shutdown and the comeback on several times even at max so seems to be running fine so turn back to the normal setting and runs for 2/3days then locks out on apparently overheat but i don't see how? any help would be much appreciated getting pretty irrate about it now.

Hello Pooly.

Appreciate you're in a bind but this really can't be answered in open fori for the safety and protection of have a go heroes reading this down the line and thinking they can repair their own boilers. Please follow the advice given previously.

Thanks.
