DHW themistor has had it. Needs new one

Thanks Dave...much appreciated.

Do you think that e-bay may be the best place to purchase a replacement?

gas4you · 18 Apr 2009

Personally I would NEVER buy any parts on e-bay, but it is up to you.

Try HERE for genuine new parts then compare the prices.

At the end of the day it is your choice

Thanks for the advice Dave.

Are the thermistors difficult to change for a novice like myself?

gas4you · 20 Apr 2009

No, but it is in a wet pocket. Follow the instructions in the MI's.

As always with Ideals, fiddly but not hard.

Thanks again,I've managed to change the dhw thermistor and I have

hot water again.I've tried re-setting the timer but the boiler has changed

from d to c and the heating has come on with still no change on the

timer from the flashing 12.00am.Oh now it's gone to 0 without me

touching anything.Any thoughts?please.
