Hi,
I have a Worcester 37cdi combi & over the last couple of weeks it has been cutting out with the E9 fault code showing.
This evening I have reset it numerous times.
Any suggestions what is causing this ?
 
What's the pressure at ? Should be a dial on the front of the boiler
 
Is that with the heating warm or cold ?
 
I would say up the pressure upto 1.8-1.9 bar
 
I have upped the pressure but as soon as i turn the hot water on it cuts out with the E9 fault code.
When I press reset the green light is lit indicating the boiler is lit but there doesn’t appear to be anything coming out of the flue although the rads are getting hotter.
 
Sorry to say time to get a gas safe engy out

POTTERTON PROMAX 28 COMBI Boiler - Hot Water Issue
Hello, I am seeking some advice, I have a POTTERTON PROMAX 28 COMBI Boiler and I noticed yesterday that the water around the house is no longer warming up. The heat exchanger has been changed 6 months ago, so I do not believe it is that. Does anyone have any ideas on what it could be? Thanks
