Hi,
We had our annual oil burner service carried out by a well known Norfolk firm last Thursday and all was great for a day. Came home from work on Friday evening to find our 15+ year old HRM Wallstar burner had locked out. I pressed the lockout button only to find it would lockout 1 to 2 mins later.
At this point I left it alone and called the company but they wouldn't attend until Monday unless I paid £125+ VAT for an emergency call out. We decided to wait until Monday as we couldn't afford the call out and it would be free on Monday if the fault was caused by the service.
Saturday morning I decided to take a look to make sure no air bubbles were present which there were none. I then isolated the electrical supply and pulled out the photocell... it was completely sooted up; I cleaned the soot off and put it back together.
Fired it back up and it worked great all day Saturday but locked out again on Sunday morning. I took the photocell out once again and it was again sooted up albeit not as bad as the previous day.
Once again it fired up fine after cleaning and continued to work for the rest of the day. The company are due to come tomorrow morning to look but can someone offer some advice as to what could be causing the photocell to soot up please?
They changed the nozzle from a 60mm to a 65mm during the service which is the recommended according to the manufacturer.
Anyone got any thoughts please?
Thanks in advance
