Have a solar hot water heating system with a wilo

Customer Question

Have a solar hot water heating system with a wilo circulating pump that isn't functioning. Gets hot & hums but does not circulate water from solar panels to heat exchanger. Is the black box ion the top the capacitor & can I just replace that. Would rather not replace pump because it would require disturbing water level in panels. Model info W 113 star 32 bf

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation. If the pump has power and isn't running then you must replace the entire pump. Do you have power to the pump?
