Probably. As long as the motor is obviously turning and operating correctly. A dry impeller will burn up and lose it's seal along the interior of the pump housing.

Find replacement impeller for Wayne pump YCB139

some pumps can be fixed if, disassembled properly in the first place. and last for many years. soo that said, search your area for your local electric motor repair shop with free testing, bring it in and see if they might have a used impeller, new shaft seal and the bearings, to get you up and running again. REMEMBER TO PRIME THE PUMP AFTER THE REPAIR ! most all pumps need water in them to work

There is a leak from the front on the pump. A steady drip but the cleaner is still moving and working properly. The front is held on by a number of 1/2 or 3/8 inch nuts. The drip is from the other end...

I recently had this happen to a fairly new pb-4 that ran dry and overheated for about an hour before I noticed it. I disassembled the volute and impeller on the front of the shaft to look at the condition of the impeller and shaft seal. There are several youtube videos that detail the shaft seal replacement. I ended up having to replace the impeller as well as the shaft seal due to the impeller being deformed. Cost me about $35 for both the impeller and seal.

It sounds like a small rock, dime, or screw may be loose inside the macerator and is rattling around. Can i extract it?

Sounds like you have a broke impeller or the bearings in the motor are bad. Clean it out real good and wash off the impeller and fill with fresh water and try it again allot of times the float will get stuck and the pump will over heat destroying the sealed bearings in the shaft between the pump and impeller this pump uses water to cool the bearings so if it has been dry running you will need to replace the pump.

Water not draining from machine . cleaned out pump but still not working.

Believing the pump to be operational, there is a possibility that the impeller within the pumb is broken or loose on the shaft. Eventho the pump motor is running the water is not being "moved" through the pump because of the bad impellers.

I have- starite pump it was working fine last night but this morning there was no pressure at all i wonder if is the water tank the pump is running fine but there is no water

It sounds like you have blown your shaft-seal. When this happens the pump runs dry. If you know that you have water but it will not pump, and all the cover and housing o-rings are good, it is the shaft seal. (unless the internal impeller is just broke, but this is unlikely)
Fix: Turn off power. Remove V-clamp holding wet end together. Remove diffuser inside wet end (need flathead screwdriver).
next remove rear electrical panel on the motor. Using s 7/16" wrend, hold the end of the motor shaft by the electrical end (where you removed the cover) while turning the impeller counter clockwise (note: some impellers have an impeller screw inside which unthreads CLOCKWISE) untill impeller is off. Replace carbon shaft seal inside. Reverse and prime and then restore power and start.

Pump was allowed to run drive for some time. Motor now works but no pumping action. Impeller problem?

If a pump runs dry it will over heat and warp the pipes and quite often ruin the seal. You should replumb the pump and replace the seal, check the impeiier while pump is open but it is more likley than not OK.

Whisperflow 1.5 pump is drawing 1/4 volume of water.

With the pump off, take out the pump basket and with your fingers
feel the front of the impeller you may have something blocking it.

The pump does not work after power cycling

This is from Danner:
The housing should occasionally be removed to clean and inspect the impeller assembly. The impeller is the only serviceable item and can be pulled out of the body. If it is worn or broken the entire impeller assembly should be replaced. This will restore the pump to original capacity. Pumps taken out of service for an extended period with fluid inside run the risk of forming a crust which may prevent subsequent starting. Saltwater should be flushed out with fresh water.

Magnet impeller assembly must be removed approximately every 3 months for cleaning in white vinegar to remove accumulations of scale or calcium. Disassemble magnet from impeller by pulling them apart (it may take a strong pull). One end cap will come off. To clean the calcium scale off of the shaft and bearing inside the magnet soak in white vinegar for a few hours and scrape it off. Reassemble magnet/impeller assembly. Do not loose (sic) any washers located between end cap and impeller.

Hope this helps!

Whirlpool Calypso washing machine keeps saying LD and will not complete its cycle. I have the motor replaced several time and I am hoping that it is not bad.....AGAIN.

LD - Long Drain - as when the pump is not running (jammed or clogged with debris, socks, or draw strings!) or when it has failed. Make sure, if you are having someone replace the pump motor, that they upgrade it with the redesigned motor that has the impeller and motor in a single part which cannot be separated. The original design was 2 parts and was a metal motor shaft into a plastic impeller socket that would strip when the impeller got jammed. There are several companies which sell the new design and for a small extra fee you can get a lifetime warranty on the pump assembly. Google for it.
