My Vokera 24 is 10years old. it has been very good up to now. It shows error code 07. The pump works but no h/w or heating. the pressure is at 1.5 bar. is it time to part with it, or can anyone help me repair it. Thanks

Don't people bother to search for themselves? 30 seconds gets me these:

code 07 means the primary thermister is open circuit, it is not able to sense the resistance through it, it is located on the right hand side of the main heat exchanger with two brown wires going to it, should have a resistance of around 12kOhms at room temp(20 degs) needs to be drained down to be replaced, hope this helps

Superficial research shows error code 07 to be an open circuit thermistor (temperature dependent resistor).

A properly qualified boiler engineer will help you repair it.

Your boiler is only 77.5% efficient - some modern boilers are above 90% efficient so start saving now.

Good Luck..., December 2015
