Hello. There are several possible issues here which are all fairly easy to investigate. Begin by bringing your pump, cord and hose into a warm space for 24 hours to thaw everything out, warm it up and dry it out. Then try it. If it works, you know you have one of the problems described below:
1. Sometimes a circuit breaker wears out and needs to be replaced. Try your pump on a different circuit, insuring that you are using a different circuit breaker. IF it works there, the solution is to replace that worn circuit breaker. 2. Check the impeller and remove any clog, blockage, debris or residue. 3. The 24 foot cord on your pump might have a cut, or a scrape on it. If it does, water is getting into the insulation and causing the circuit breaker to kick. Check your cord thoroughly and if you do have a break in it replace the cord or repair it with a waterproof repair. 4. Your pump motor may be worn or faulty or have a water intrusion. In that case the only fix is to replace the pump. 5. The drain hose could be frozen. If it is, that blockage could cause the breaker to kick. Always ensure that the hose runs consistently downhill.
