Hi all
i have a regular customer with a Powermax 155x OV with pump and programmer.
i changed the flow switch as it was sticking - i also changed the dhw pump as it was faulty
after this there was minimal improvement.
i then removed the plate and descaled for a day using fernox ds-3 - this now has full flow through it.
i refit it and checked but still only luke warm water. I also descaled the blending/mixing valve at the same time.
on the wet side of things there is nothing else i can change.
am i missing something.
