Worcester Greenstar Ri kaput - two blue light flashes

[NormanSpencer]

Hi there

I think our dishwasher tripped the kitchen circuit (I am almost certain it was the dishwasher and not the boiler tripping the circuit).

This caused the boiler to behave as follows: a long pause then two quick flashes from the blue fault indicator in the middle of the unit

With the thermostat to maximum and the timeswitch set to on and when starting the unit up:

- the unit green (ignition?) light comes on, the unit makes 'boiler' type noises, and (I'm almost sure!) the radiators get warm. The only problem is the flashing blue light in the centre of the unit: off for five seconds then two blue flashes per second, and repeat.

Can anyone help?

ps I have tried turning the temperature knob anticlockwise to 'reset', but that seems to not change anything.

Many thanks

Norm

Try powering off the heating system at the fused spur for ten mins and then see if it clears, poss power cut has caused the boiler a few problems, usually you would only get two flashes when in service mode. Worth a try first, hopefully nothing damaged on pcb?

Thanks 1983.

Was just going to do as you said, but found that I now have a happy boiler with the blue light on glowing away constantly.

It's a bit odd, in that it's been over 2 hours since the power cut, and I only checked it 10 mins ago.

All's well that ends well...

No probs, glad you got it sorted. Maybe voltage spike?? Keep an eye on it though.
Cheers
