Vaillant boiler decides to stop working on New Year's Eve. Regularly serviced (last time 07 June 2024).
No display, but pump sounds.
No chance of an engineer until at least Thursday.
Not a happy bunny.... :(

There is a way to get trouble codes on my Vailiant boiler. Involves pressing front panel buttons. Google your boiler model number and something may appear.

It's a Vaillant Ecotec Plus 837. Display should be automatically showing, I think.

In which case, it should show an 'F' code, which you can decyper on t'interweb.
Then once you know what it's whinging about, there should be an engineering screen that you can enter by pressing various combinations of buttons. Once in the engineering screen you can scroll through various parameters to see if they make sense.

Screen is completely blank. Not lit. Pressing buttons does nothing.

Not familiar with your boiler. On mine, (an Ecofit 412) the LCD display is permanently on, but to get the backlight to light you have to push any of the front panel buttons.
If the display isn't lighting up or showing anything then I'd be looking for an electrical fault in the mains supply to it. Either an isolating on-off switch somewhere (there should be one) or a fuse/circuit breaker. But you say the pump is working, so perhaps not.

You left sodding of the title.

Not sure that will fix it...

Vaillant engineer just called – PCB dead. Now replaced and all is good! :y
House defrosting... ;D

My sister has had 2 replacement PCB’s in her Vaillant boiler (same symptoms as yours), both times covered under her home insurance policy. The first time it happened was after a power cut and the second time it happened was after a dodgy socket tripped the mains. Both engineers told her to always switch off the boiler on the boiler switch, not the isolation switch or the mains trip. He said that they are prone to spiking when the power goes off for whatever reason, so there could be some truth in that, although in her case she was powerless to prevent it.
I’d better add for safety reasons, that if anyone plans on working on the boiler, that the isolation switch or mains trip should be switched off once the boiler is off, just in case anybody misinterpreted what I meant.

Could you install a surge protector?

Yes, I believe you can. :y

My vaillant has been chugging along nicely for over ten years. Never had a service and been through plenty of power cuts. Has to work very hard to keep this leaky old place warm.

Hope you've got a carbon monoxide detector. :) Though my old service engineer, who has since retired, reckoned that the domestic ones weren't worth a shit.
