IT SOUNDS LIKE IT HAS LOST PRIME. YOU NEED TO PRIME IT BUT IT SOUNDS LIKE YOU NEED TO ADD AN INLINE CHECK VALVE RIGHT WHEN IT LEAVES THE PUMP. NOT GOOD FOR IT IF IT IS TRYING TO START WITH ALOT OF BACKPRESSURE ON IT. IF THIS DOESNT FIX IT LET ME KNOW SOME MORE DETAILS LIKE WHAT KIND OF PUMP IS IT. HOPE THIS HELPS, JODY

No water from drilled well, intermittent.


1-If everything has been replaced can you turn water off and check air pressure in the water storage tank. the bladder may be leaking and causing it to work some. A 40 gal tank should have about 28 psi of air in it. Also you can press on valve at top of tank to see if any water comes out will let you know if it's bad. Air should come out at top and no sign of water from valve on tank..

2-When you changed pumps did you replace the check valve in top of pump. Some pumps I have had to pull back up and add a check valve to pump.

Most pumps have a check valve on top with a retaining clip holding it in. And they work sometimes and some have to be removed and add a brass check to pump and connect to water pipe.

My Simer 2300-03 has been great except that it overheats after awhile. Too little water??


Yes. I recently used a similar pump (Flotech 1/6 hp) running for about 24 hours - but it came with this warning "don't use continuously unless submerged in at least 4 inches of water". This is because it will easily overheat, as yours has been doing. Mine worked for pumping water out of my basement (not the speediest little pump), but only because there is a sump hole in the floor where the pump could remain submerged.

Hayward Self-Priming Pump with AO Smith 1 HP 56J frame motor. Stopped moving inground pool water. Added water to pump basket (low). Turned on pump, return jets sent "bubbles" into pool, stopped, then...


the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck

My new AO Smith 2HP pool pump won't pump water, just hums


I'm guessing that you replaced the motor that goes to the pump, not the pump itself. You know the motor works just fine. Is the motor rotating in the correct manner(clockwise or counterclockwise) in relation to the rotation of the pump? Have you checked the pump to see if the impeller is working/rotating? Is the motor hooked up to the pump correctly, so that the motor is turning the impeller? Are all connections to the pump tight, so there are no suction leaks? Have you primed the pump and purged it of any air locks?

I bought this dishwasher 5 years ago and was kept in the box until last month. I installed it, turned on the water and no water is being pumped into the unit from the water release valve in the dishwasher....


You will have to check all the connections visually. Since you know how to use a meter, see where the current stops. See if there is current coming from the control board to the pump. the water inlet solenoid valve should "free flow" water into the machine. the pump recirculates the water for the wash and rinse cycles and pumps the water out of the machine to the drain. It is more likely that that water inlet solenoid valve is where the problem is.

Flotec Sprinkler Pump not priming


it might be that the pump is prewired at 230 volt and you are running a 115 power supply to it, if motor just humms and little water comes out this might be your fix

Water is not pumping into dishwasher


When you connected the water line did you remember to turn the water valve on?

Ice maker doesn't work


  • yes this is the water valve. it does not pump the water but it does turn it on and off like a faucet.
  •  you can purchase the water valve assembly at any appliance parts store or website. 
  • you will need your model number. 
  • if you need help just let me know.
