What to do if my Danfoss Water Pump is receiving a faulty input control signal?
A faulty control signal is being received at the pump. Verify that the input signal being received is correct and identical in both directions. Adjust, clean, repair, or replace the control module as necessary. This could be due to binding or broken linkage (MDC), a faulty or inadequate electrical signal (EDC), or blocked or incorrectly orificed control lines (HDC).
