Boiler error msg being charged for 6 months

[Choppychop]

I’ve lived in my new build for 13 years, boiler installed 12 years ago. Never had an issue so I guess I’m lucky. Never had a service. Showing error code E 50. Boiler company (the boiler and installer same company not a random plumber). Being offered close to £700 upfront to come look at it and repair it or slightly less over 6 months (£75 month) to repair and if not reparable will put £700 towards a new boiler. Does this sound reasonable? I worry that it’s fixable and could pay a professional half that to fix it but it’s so hard to trust anyone these days!

Get someone out independent to look at it but honestly it’s ridiculous you’ve never had it serviced and if it costs you £700 you’re still ahead of the normal costs for 12 services

Have you googled the make, model and error code? (Sorry if that is obvious).

Yes I have and it says to try resetting which I’ve done. It actually seems to work with the radiators which have worked as normal. Hot water not so much. Zero hot water.

That’s true! I feel very lucky that it’s taken twelve years to have an issue! It’s worked perfectly until now.

Diverter valve?
Find an independent plumber.

What’s a diverter valve? I’m a clueless singe girl with no idea…

The diverter valve diverts the water to radiators/ water/ both. They can stick and need replacing, which is why boilers need regular servicing.

Wow how stupid not to have it serviced, should your boiler be a cause of a fire bang your insurance will drop you and heaven forbid the fire spread to other houses your in a huge pickle. Anyway I wouldn't bother repairing one that old 12 years is good for a boiler. We've just had a new one put in last month it also made it to 12. We decided to just get a new straightaway once it started failing because a friend has spend more last year in repairs and now regrets the waste as once one thing got fixed the next thing went it being so old

Was just coming to say that! It’s something that sends water to both heating and HW. I got a local plumber out.. 5 min job cost me £50. Try a local plumber.

Seriously? I am a 70 year old woman who has a boiler in my home. I consider it my responsibility to read the instructions for all my appliances and also to pay attention to safety measures including servicing. I hope you have smoke alarms that you clean and test regularly and a carbon monoxide alarm.

Gas safe engineer, not a regular plumber.

Also live in a new build (7 years old). Our boiler stopped working a few months ago. It cost about £200 including part for a local GasSafe (or whatever it is now) engineer to come and look and it and repair it.

Gas safe engineer will sort this. Ours charged £30. It was the diverter

As a fellow clueless single girl here, I’ve saved a heap the last year using chatGBT to find the root cause of errors on my boiler etc then using YouTube videos for guidance on how to fix them. My boiler kept playing up for months, turns out it was fine after I changed the batteries in the control panel on the wall 😂

Yes I have smoke alarms and carbon dioxide alarms too. I’ll get my boiler serviced from now on!

A quick google, reveals that E50 is a fault on the domestic hot water circuit, often a sensor or sometimes the control board. The boiler company is trying to rip you off, you may need a new boiler, but probably don't and a sensor and or control board will be well less than £700. By the way, regular servicing will not affect sensors or electronics, servicing checks the flue is clear, there is no CO leakage, on old boilers that the pilot light and thermocouple are ok and on combis that the expansion vessel doesn't need pumping up. A good adage is always" if it isn't broken don't fix it".
