Is not working and cuts out with an L9 code. Will not start again for some time until the heat exchanger cools, which is a good while.
Will fire up if left alone, pressure gauge fluctuates wildly before cutting out. It is overheating on the heat exchanger?
Manual is indicating a thermistor issue? but maybe be the pump or PCB, any ideas?
I would be grateful of the wisdom of the forum can advise
