I am very confused now
seems fan is rotating against the exhaust flow
I've tried reversing the polarity
BUT IT STAYS GOING THE WRONG WAY
I do not understand!
hi there
my DHW only runs for about 20 seconds before it locks out
had a dodgy exhaust fan for a while but that is working now
CH works well enough most of the time
water flow switch seems to be operating ok
confused!
cheers for any advice
