not sure if this might help, but i had a problem on pcb,and traced it to a faulty capacitor and changed it, but have 2nd fault same as you with hot water, noticed pump jamming and running slow, suspect restricting flow to heat exchanger, water ok if flow turned down,
going to change pump front with known good one, will post results.

Mine is exactly the same. Could it be the cold weather do you think?
