Worcester Bosch heating not staying on

[Rob Wentworth]

I have the WB green Star 24i with a manual timer. We only have it set on/off and not use the timer, the issue we have is that it runs fine but when the heating switched off it doesn't come back on. The only way is to push the on switch on the timer upwards from the on position and it fires up, not a huge issue but annoying.

Further to this, it has starting to only come back on if I start messing with the timer settings which seems wrong as we never use the timer.

The water pressure is fine and we have hot water.

Can anyone suggest anything please

sounds like the timers at fault

best to get a gas safe engy out to check it function
