Hi all, i have a potterton 28 he+ that been giving me an random e168 errors.
so far Ive replaced the actuator, diverter cartride, pressure switch, temp sensors pcb and room stat (salus wireless). doesn't happen as frequently now but still there. usually more after having used hot water.
im also considering that the diverter valve body may be letting water by the cartridge and not sealing properly.
any other suggestions?
after a while of it locking out the pressure drops slightly too (apx 1/4 bar) and need topping up. could it be related or just addition ev needs a top up too?
