Had a service call on a Rinnai RUC98i with a wilo recirculating pump that wasn’t working. Dedicated recirculating loop. Checked the dip switches on the tankless and it was configured properly. Redid the wire nuts and the pump kicked on. Pump failed to operate more than the day. Any tips or recommendations would be greatly appreciated. Never worked on this before.
