British Gas 532/i No Heating but there is hot water?

Hi,

I have a British Gas 532/i boiler which is approx 3 years old now with a WR1 wireless receiver and a RC5 transmitter.

The problem is that at the moment I cannot get the heating to come on.

If I turn a tap on then the boiler starts up and there is hot water.

If I turn the terperature on the RC5 remote up then a flame shows on the display indicating that it the boiler should be told to come on and then the receiver unit flashes to confirm it received the signal. The "Heating on" led on the receiver is then switched on but the boilder does not start.

I have topped up the boiler water so that the pressure is ust below 2 bar.

I have tried turning it off an on again and have pressed the reset button. The radiator dial on the boilder is set to 6 which is one below max as is the water temperature dial.

Ther display on the boiler shows 58 and there is no error message or anything flashing.

The light on the front of the boilder between the dials is blue.

The batteries inthe RC5 look fine and it seem to transmit a signal ok.

No idea what else to try! Any help appreciated!

most likely a problem with the timer / thermostat.
hold in the spanner button for 10 seconds and it will light up. this puts the boiler in service mode and the heating will run for 10 mins. if the heating comes on then you can be pretty certain that there's no problem with the boiler. if it doesn't work then you most likely have a problem with the diverter valve.
