If you are talking centrifugal pumps then the system has to be completely leak proof as air getting in will allow water to drain down
the foot valve ( check valve) can be held open by gravel, dirt or sand
the impeller seal can be leaking
the suction line to the water can be leaking letting air in

Idle fine, then run ok for few minutes, then cant go over 15 mph,new filter, new supply pump, suspect turbo or injector pump


Hi , you probably have water that's went from the tank to the pump. DIESEL PUMP. The worst thing that you can do is let your fuel go way down low and some water is taken in with fuel + water . The fuel pump is a mechanical pump with moving parts and you can't let water in . Certain pumps ,diesel pumps have a latch valve and you don't want water to sit for any length of time in the surrounding wall of the valve as it will rust this may cause the valve to stick then your car may go to rev excessive sometimes high revs , i mean screaming rev's. Please get the pump checked.

Pump won't come on, it has power to it, also the


The water from the relief valve means the boiler is very full, lets work on the water problem first then we will go to the pump.
IF the machine is not turned on does water flow out of the relief valve? ...if yes then check the manual fill to make sure it is in the off position. If no then we will need to check the level probe and or the inlet solenoid, because something is telling the machine it needs water.
For the pump is there any sound from it when you press the brew button? ....If yes then it might be blocked and you will have to remove the ring collar from the brass head, to remove pump from motor then check to see if pump head rotates, note direction on front of pump head. If no then you might have lost a fuse or there is a loose connection at the main box.

Dishwasher is running through the cycles, but no water is being pumped into the unit. water supply is fine. Is this a common pump problem?


This is either the inlet valve (solenoid valve) or the timer. Water is not pumped in, it flows in under it's own pressure when this valve opens.

On the solenoid valve there are two electrical connections, you could remove these (often spade connections) and connect a mains supply - if it opens then the valve is fine so it is the timer.

A solenoid valve is a cheap and easy to swap component and any DIY'er can do it. It is located right by the inlet pipe (it is part of the inlet pipe assembly) the screw part which the cold water pipe is attached to is the solenoid inlet valve.

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.

We use the Cascade tablets but they don't dissolve


Either:

1. the water does not get into the dishwasher open the dishwasher 3-4 times during cycle, you should see some water at least once, if not - check water valve, water level float and water pressure.
2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.

Good luck,

Tablet will not dissolve


Either:

1. not enough water gets into the dishwasher. open the dishwasher 3-4 times during cycle, you should see some water on the bottom at least once, if not - check water valve, water level float and water pressure.
2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.

Honda excell pressure washer does not have pressure


if the machine is running on suction, ie sucking out of a barrel there may be an air leak on the suction hose or pump. it will pull air easier than pulling water .

put the machine under mains water pressure, hose pipe straight from tap to pump.
check all around the pump and inlet pipes for leaks.
if water leaking this needs rectifiying for it to work on suction.
run the pressure washer while on mains pressure with the hose on, does this make a difference?

if not then probably the unloader is stuck in the pump head. remove unloader , clean and replace it
parts breakdowns are available on the internet for your machine.

possibly valves stuck, or the valve springs have broken, seen this quite few times on these machines. if so replace springs .

These sort of machines do not last very long anyway, about 50 hours use if your lucky.

My pool pump won't prime


If the pump is above the pool water level the it is unlikly that the tank will fill completely with valves open (which is ok).Most pumps are self priming and will pick up a prime with water level below suction inlet on strainer. Try starting on main drain again and slowly open skimmer line. Did you remove water from skimmer line and winterize(if in cold weather climate)during closing?.I know this sounds stupid, but make sure water level in pool is well into skimmer. If air situation remains after scspriggs' and these thoughts then prepare for a pressure test on skimmer line to determine location of leakage.
