Baxi eco 80 CH too hot, water just warm

[radsbow]

I'm i need of some help please,

My combi is set to minimum, but when the combi comes on, within 10 mins, all the rads are way too hot, in fact you can't touch them as they are too hot. I also noticed that the water just gets warm rather than hot as it used to.

I've not let the combi run more than 20 mins as am worried it wont switch off!!

Has anyone any suggestions as to what might be the problem?

Can't think offhand of a single fault which would make it do that.
Can you not turn the radiator temp down on the front panel at all?
Temp sensor a suspect.

Tap water - check diverter operation.

HI There,

I can turn both the switches down to minimum on the front panel of the combi, buit neither seem to make any difference to the heat.

The puzzle continues.....

Just switched it off at the power socket, then swithed the power back on, then the CH and now it keeps lighting up for 11 seconds, then switching off for 10 seconds, then lighting up again and so on - its doing this continuously!!

First problem is probably the single temp sensor (NTC thermistor)
Second problem, probably not sensing the flame.

You need professional help!
