Worcester Bosch Heatslave 26/32 heating not starting

[thomsewe]

Hi All

I have a Worcester Bosch Heatslave 26/32 which has proven to be a very reliable boiler.
but has developed a fault over the last couple of months.

The hot water works fine with no problems.

The timer turns the hot water and and the heating on and off at the correct times.

However although the heating is indicated to be on by the light on the front of the boiler it does not always start.

Some days it works without a hitch but others can be more of a problem.

A few gentle taps around the control box area gets the boiler working as normal.

I am thinking it is one of the relays on the controller PCB that has developed a problem so need to replace the board?
although have read on this forum about diverter valve problems could cause similar symptoms (although not sure why taping the control box would start the heating)

Wife is geting fed up now and asking het to put another jumper on as it saves oil does not wash any more!!!!!!!!

Please help me avoid the divorce court!!!!!

Thanks Tom
