Question about Heating & Cooling
I have a worceseter combi boiler and there is a message flashing - PO8 and H7. what does this mean?
Find the model number and look to the link to download the i/o manual. there are trouble shooting sections that will tell you what the various error cores refer to, and flow charts to check the system malfunctions.. Given that the error codes vary from manufacturer to manufacturer and even between models without the manual it would be guess work. When all else fails Read the Instructions and follow the sequence of operation to find the fault.

Either on the inside of the door or in your manual will have a list of all the codes. You could try turning the unit off, not while its in operation, and turn back on in 20 seconds. But first find the meaning of the codes, or faults. They will be listed. Unless the code is stupid simple, contact a pro. CO and fires kill if you don't know what you're doing
