Hi,
I have a 20 year old system - Potteron wall hung with 2 x 2 port motorised valves.
I noticed a faint burning smell yesterday from the airing cupbiard where the pump and motorised valves are - Also the electrical isolation switch is there.
And noticed later in the day that the lights on the programmer were not on, and there was nothing working.
I changed the fuse, and after sliding the controls over to ON the fuse blew.
I have tried having heating only and hot water only and always fuse blows.
I have even changed one of the synchron motors as thought the old one smelt a bit burnt.
I changed the other synchron motor last year.
I have undone the screw on the front of the pump and rotated the inner screw to ensure that it isn't stuck.
If anyone could offer any advice , I would be extremely grateful.
