Upon arrival I found Geo cube locked out on high pressure. Reset fault and system locked out almost immediately. Found Load Pumps not running or getting voltage. Traced wiring back to cube and found (2) high voltage fuses blown (10amp). Replaced with new but before so we checked pumps. Found lower load pump is grounded. Returned power to system and could see pump sparking. Removed wiring from bad pump but kept power to the other pump so system can remain running. Continued to test and system satisfies in heat mode. This pump was added for ac operation because we didn’t have enough water flow. System will heat with pump down but suggest getting it replaced ASAP. Called WF for warranty status and found pump warranty is 2 year, which ended a few months ago. Quoting customer to replace Load Pump. Customer approved replacing pump, collected deposit. He said they are leaving for vacation on 10/23 and won’t return for a few weeks. If repair could be done before they leave that would be id
