I have an 1800 rule pool cover pump and it quit working, just quit

It sounds like the pump motor has shorted. Probably time to invest in another one.

SOURCE: broken garden hose adaptor

We have the same pump and problems. I have attempted a few fixes with PVC sealant and hose clamps to the current adaptor, however the adapter is still continuing to crack. The adapter is removable- carefully so as to not damage the small eyelet it attaches to, (or in our case, it came off on it's own) and can be replaced by any adapter that fits- they can be found all over at lowes or home depot. I am personally going to try using a broken hose and clamping it directly to the eyelet. This is not a good reason to buy a new pump- they fix too easy!

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.

You are probally just getting an air lock and can fix this by taking the hose off till it's under water or hold it upside down in water till it starts. If you hold the cord while it's in the water an just make sure it's taught you should be able to feel the vibration through the cord to tell if the pump is indeed running while under water.
If this does not help you may have to take the bottom end apart and check the impeller for clogs.
I hope this helps and good luck.

Your float switch is stuck and/or the hole that lets water in and out is plugged. Clean the switch.
