BAXI COMBI 80HE - PLEASE HELP GOING MAD!!!

[Canadajim]

Hi,

I have just tried to activate the central heating on our Baxi Combi 80HE and have the following indications from top to bottom on the neon indicator panel:

DHW neon (top-most with tap symbol next to it) GREEN CONTINUOUS

FLAME FAILURE neon: RED CONTINUOUS

FLAME neon: GREEN FLASHING

"ON" neon: (to left of CH temp knob) GREEN FLASHING

Basically the rads are not heating up at all. The thermostat clicks when passing a certain temperature but the but there is no iginition of the burner. However, when I turn on the taps the boiler ignites and I get hot water (have checked this by taking the housing off and observing flame viewing window)

I have also re-pressurised the system to ensure the pressure indicator on the boiler is in the green zone (it was reading low initially)

If I run through the neon fault indications on the inside of the boiler housing it indicates DHW flow switch but I fail to see how this would stop the rads from heating?

Can anyone who is in the know give some advice?

Thanks.

Probably the diverter stuck, pretty common on these.

So if the DHW flow switch is stuck, is there any way to unstick it or is it a straight replacement? What is its location on the boiler?

Thanks again.

Hi All,

Yep, its a BAXI COMBI 80 HE PLUS - as placarded inside the lower door that drops down to allow access to the primary controls and neon indicator lights.
