Boilermate 2000 blank LCD display and no heating Empty Boilermate 2000 blank LCD display and no heating

Hi, looking for some advice.
Everything was working fine this morning, been out all day, and now come home to a cold house.
Checked the boiler and it was firing and Honeywell thermostat was demanding heat, so checked the boilermate.
It had all 3 LEDs on (even though no hot taps running) and LCD screen was showing ON with the 3 bars. I tried both buttons and the LCD display did not change. I switched the whole thing off, left it a few minutes, and switched back on.
Now I have blank LCD display with 3 LEDs on. I hear no movement from the boiler pump or CH pump, but the hot water pump again sounds like it's running with no taps on. When I do run a hot tap I do get hot water for now at least.
I'm guessing the board is done for, but I'm concerned about just buying a new one in case something else (failed pump?) has caused this and just breaks the new one.
Any advice?
Thanks

Boilermate 2000 blank LCD display and no heating Empty Faulty GT155

I know you already found me and we have discussed this but for the benefit of other readers I can confirm that the symptoms you describe are a classic indication of the GT155 being faulty. See the video on my website which shows typical symptoms. www.murraymartin.co.uk

If a pump fails it might pop one of the chips near the green leds at the bottom but it is highly unlikely to make a pcb fail in the way you described. Regards Murray
