Hi Sunshine, this is potentially bad news if it is the main tank leaking. Terminal in fact. It might, however, be something fixable like an automatic air vent. Can you see/find the source of the leak? I suggets you try to find the drip then follow it up (using a torch and mirror if necessary) to find the origin, and post here again with your findings...

Cheers, Mike the Boilerman

Thanks Mike. I haven't been able to find the leak because I thought I would wait until my husband came home, he is more confident taking the boiler cover off etc. However, what I have been able to establish is that it only leaks when we have the water/shower on, not whilst it is heating the radiators.

I have got a British Gas engineer visiting tomorrow morning to look at it, and have been sold there homecare package! Although I feel sure when they realise it is a powermax they won't want to cover it.

Here is praying it isn't terminal!!

Hi all

I have a Powermax 185 boiler, which is serviced annually. However, lately I have been having many problems with the boiler igniting. The fan runs, and it attempts to ignite, but does not do so straight away. Sometimes, it does not ignite altogether, therefore no hot water or heating!!

Could someone please help. Any suggestions welcome.

Many thanks

Hi everyone, BG visited today to carry out an inspection visit on our 155x to see if they are happy to take it on one of the monthly plans. It failed because it needs a new heat exchanger apparantly (even though currently working very well). Could anyone advise of a part number for such a thing so that I can get a good idea of prices. BG suggested about £230 (quote to follow) to change heat exchanger. Reasonable or over the top?

Thanks

Try Heateam, they will come out and fix your boiler regardless of how many parts they use for a fixed fee. Also the fee will insure the boiler for the next 12 months. My Powermax 185 packed up last night.
Telephone: 0844 871 1545.
Hope this helps

I have same problem as many on here with a powermax 135 Banging noises/explosive ignition and mine also recently makes a whistling sound like a kettle! this whistling seems to be when the boiler has been on for a while and reaches the required temperature, heating and hot water both working though despite this..... maybe not as much hot water as before problems.

I have had a heateam engineer come out but was unconviced he knew what the problem was, firstly he pointed to a green ignition box inside the boiler a (pektron timed ignition sequence unit), and said he believed it to have a hairline crack said he will order parts until then he has issued an unsafe warning and told me not to use it. How ddoes that expalin the whistling?

Many thanks
Keith

You can read several posts that relate to the whistling noise.
The majority of posts suggest that its the gas/air mixture valve thats at fault.

As for hairline crack!!!! How could he possibly know that?.

I've also had the ignition problem and it was down to the main circuit board CAP had blown (a very common problem).

Hi
I had posted a message earlier. BG came out to look at problem and changed the PCB board. Have water and heating finally! but now we are experiencing a loud bang every morning, waking up the whole house.

I believe from reading the other posts that it may be kettling. Could someone please confirm if it is and if so, can it be fixed and how?

If you have a 185 then there is no physical way of descaling the unit. What I did (and it has worked for now) is to fit 2 prof electronic descaling devices to the boiler. One at the cold water inlet and another just above the hot water outlet to the blending valve. It has stopped most of the ketling noise.

Keep the circuit board and look on the net for a company that repairs them (cant remember who they are now!). It will save you loads of money and you have a spare!!!

Take the time to read the entire thread if you can. It will give you an idea of what to look for if something else goes wrong.

Dont quote me on this but banging can be caused by faulty or dirty electrode.

Hi, not sure if anyone can help.. I have a Powermax 140 which heats water fine, but the heating doesn't work. The pressure dropped so raised it above the red line again, still isn't working. Anyone got any ideas what the problem is, I haven't got a clue!

This will be because the CH pump is not running. Could be jammed (free it by removing the big screw in the centre and rotating the motor shaft), or it could be getting no electricity due to failed CH channel on the programmer. Are all the lights still working correctly on the programmer? If not then a new programmer should fix it.

NEED HELP!!! Powermax 140 boiler

hi i need advice for my Powermax 140 boiler. i am with BG homecare and i have had 12 tech visits and still my boiler is still not working properly.

it was whistling / locking out / and now back feeding throught the header tank in the loft and out through the open vent over flow.

i have had new turbolators fitted, gas valve, room thermostat, fan, pcb board, and CH pump fitted. The whistling has stopped, lock outs have stopped (well i hope!). when the boiler reaches working temp, i hear gurgling noises through the pipes and radiators and thats when i notice the water is back feeding through the header tank in the loft, after it has stopped i notice there is alot of air in the system and i have to bleed some of my radiators. the last visit i had a manager out with a tech, and they are playing the joker card saying there is some sludge in the system and this could be causing the back feed and of course the power flush is not covered under the contract-they want £600 to flush.

im not convinced and think there is something else causing this.

Any advice would be most helpful, i hate to comment on this but i think the BG techs are not clued up on this type of boiler!

any advice sean or mike?........anyone please helo...ta.

Hi - I have a 7 year old Powermax 185 which is banging and clattering. We are also finding that we get luke-warm water downstairs, but still get warm water upstairs . The upstairs bath and sink is closest to the boiler.

Reading the other threads- does it seem most likely that the Bleeder valve is at fault? We do not have a water softener- is it likely to be choked up with calcium?

Hope that someone can help please?

Thanks in advance.

We are in the west London area.
