Customer:

Hi . can you confirm the boiler pressure , please

JACUSTOMER-4262863a- :

1.5 bar

Customer:

Ok thanks. 02 is flame detected with boiler off . this will be either a faulty flame detection probe or a faulty board.

JACUSTOMER-4262863a- :

What is 02

Customer:

Hopefully it will be the probe as the board is expensive

JACUSTOMER-4262863a- :

What is 02

Customer:

Was it not 02 ,sorry got a lot happening here . ok let me check for 03. Thanks

Customer:

Ok . high limit overheat stat has operated. This will be down to a faulty thermistor/temperature stat . or your pump has failed .

JACUSTOMER-4262863a- :

Thanks. Shall I change the temp stay then?

Customer:

I would check the pump is spinning first . there is a bleed screw on the middle of the face of the pump . if you undo this ( a bit of water will release , get a towel ) and reset the boiler , insert a Phillips screw driver into it and see if you can feel the motor spinning , also , if you can see if you can stop the motor by pressing lightly. If you can stop it then replace the pump . if the pump seems ok , then replace the heating stat .

JACUSTOMER-4262863a- :

Ok will do

JACUSTOMER-4262863a- :

Thanks for the advice.

Customer:

Your welcome

Customer:

Would you mind rating me , thanks

JACUSTOMER-4262863a- :

o i take the bleed screw all way out?

Customer:

Yes

Customer:

Some pumps will drip , some will squirt

JACUSTOMER-4262863a- :

I have noticed that the letters FI on display which means purge but it stays purging for 2 mins the shuts iff

Customer:

Ok ,purge is normally purgining the gas line

Customer:

Do up you mean f1 or f11?

Customer:

Does the boiler go to fault on hot water and heating?

Customer:

Is it a new installation?

Customer:

Hi , do you still require help?
