Baxi Potterton Powermax HE 115 - fault code E03

[Soulseeker1972]

I would appreciate any help you can give with the following issue we have on our Baxi Potterton HE 115 Condensing boiler.

After approximately 10 minutes of the heating coming on and the burner lighting the fault code E03 appears and the burner light goes off.

The manual says that the flow temperature is abnormally high and to check the pump/3-way valve and water pressure. As it is a Baxi Potteron boiler no local heating engineer will touch it so we've had to pay for a 1 year contract with the "specialists" if I may call them that to repair the boiler as and when it breaks down. They've been out twice already and checked the pump etc and have said there are no issues with it and that the boiler is fine. They believe that there is either air in the system (I've bled the radiators where there was a bit of air in one of them but it has made no difference) or there may be a blockage in the pipework causing the cut out and have suggested we get it powerflushed. Bearing in mind the cost to get the powerflsuh done I would appreciate any advice/comments on this.

I would add that we have no issues on the hot water side when the heating on the control panel is turned off and the burner comes on and off like clockwork.

We have already spent a considerable amount of monies in the past on previous issues, which resulted in a new boiler 2 years ago but the problems seem never ending since this September. It's got to the point we may just draw a line under it and get the boiler replaced with a different make altogether.

Any help you can give would be much appreciated!

Bypass ???

Hi soulseaker .. sounds like you have a BG contract .... Why not phone them and ask them to prove that there's a 'sludge', 'blockage' problem! And ask them to prove it!

That in mind though it does sound like that you may have circulation issues ..

Not familiar with your particular boiler, however replacing the boiler, heat source, I doubt will resolve any circulation issues ... IMHO

Thanks for your comments Poxi and diamond gas.

I will touch base with them again and get them out - however I'm losing faith with them and the Baxi Potterton boiler as it's constantly being fixed with one problem after another.

I'm interested in your comment that by replacing it with a new one won't resolve the circulation issue as we're more likely to go down this route now. With every quote we've had so far (to replace with either Vaillant or the favourite so far a Remeha) they've quoted for a thorough powerflush and system water treatment which would surely sort out any lingering circulation issue out?

You'd like to hope so soulseeker .... A good clean out is certainly a good thing to do before fitting something new in it's place for sure

Steve,

Thanks for the response.

With persistence I've managed to get them out again tomorrow so hopefully there will be some light at the end of the tunnel - however I'm not hopeful based on recent experience! Will let you know how I get on.

On a separate note do you have any experience of the Remeha Avanti combi boiler range as this is is what we would be looking to replace our Baxi Potterton with if it comes to it? Probably the 35c unit. Very experienced installer and they've installed some 80 units over the last 3 years.

if you clean your system well ,any boiler will run for a long time without giving you a hard time ! My first choice is WB but every one has his opinion over everything really

I've seen some good reviews on here regards the Remeha range ... Personally I'm a maintenance & repair engineer these days and leave the installation to installers My backs done in humping old boilers off walls and floors (said with tongue placed firmly in cheek)

Just to let you know we have no hot water at all from the boiler now - it automatically comes up with the E03 code. The only way we can get it is through the immersion heater. Does this mean it is definitely a fault with the boiler now? Still awaiting for an engineer to come out!
