I have replaced two DX300 washpump motors in 6 months and both times the front bearing has seized due to water contamination.This is due to the mechanical seal leaking past and entering the bearing.Is this a common occurance with these replacement motor/pumps?

Not at all you have a defective seal on the washer. I would contact the maker of the unit and see if they have a recall on this particular model for the reson stated above

Hope this helped

What is causing a whistling sound when the lg dish washer is in wash or rinse cycle but not when emptying wash or rinse water?


This does sound like the problem caused by the washer motor front bearing. The sound is more a whining sound. The bearing is of poor china quality and does start giving problems due to the water seal of the impeller that has the smallest water leak. The drop of water ends up on the front motor bearing causing the bearing to eventually pack up. You need to replace the water seal that is in the plastic impeller housing. Also replace the front motor bearing and this bearing is relatively cheap. Not necessary to replace the complete motor and impeller housing. Just the bearing (number 608) and the water seal (impeller housing includes seal)

this ice flaker has one of the worst screw set ups you could think of it is normal for the lower seal to fail then water gets in to the lower bearing and that loads the motor down and some times you will here the clutch gear clicking and strip out . It is not worth fixing this problem as this will happen many times over it's service life,i worked on a machine like it and i had a custom top bearing made and still after 6 months it failed again from lower bearing seal what causes it well the machine screw gets out of shape and loading due to incorrect water level setting

My 2hp hayward super pump is just out of warranty and has begun leaking. It also has a high pitched whine which comes and goes. Does that mean waters gotten into the bearing and if so can I replace it?...


Yes, water may have entered into the motor, mainly into the front motor bearing, where it washed away the lubrication. This will only make the noise louder and will need to replace the bearing. otherwise it will eventually seize and no longer work.

1982 Yamaha Seca XJ750 front brake caliper seized up


Hi, Shooterhead and the usual suspects are:
1. Piston stuck in the caliper due to contamination.
2. Piston stuck in the master cylinder due to contamination.
3. Incorrect DOT # of brake fluid.
4. Warped or bent brake rotor.
5. Incompatible brake pads.
6. Incorrect caliper spacing.
7. Not enough free play at pedal or lever.
8. Collapsed brake line inner lining.
9. Excessive heat buildup due to riding the pedal or lever.

My AO Smith motor sounds like it is jammed. When the pump starts you can hear the motor buzz but it wont actually turn on. then after about 5-10 seconds the put shuts completely off. I replaced this pump...


sounds like jammed or bearing seized water could have seized bearing spray and lube bearings than try by hand [with a non marring pliers or if can grab impeller] and try to turn motor by hand to loosen motor-- when motor doesnt turn it heats up and will turn off till it cools down this is a safety u may get lucky and the motor will run if it hasnt shorted out a winding

The pump has been louder for a couple of weeks and after I stopped it to clean the spa filter, it won't start. Sounds likes it's seized


I had that happen when the spa was off for 10 days. I took the pump and wet end out, and managed to turn the shaft to free it. It has rusted up in place.
6 months later it started the loud noise and started getting worse - the motor bearing at the wet end was seizing up. I replaced motor and wet end just in time.

Whirlpool Pump - Hums, no water flow...


The impeller and/or motor shaft is stuck or seized. If accessible you can try rotating the motor shaft with a visegrip plier or similar tool to see if it will come lose. Otherwise you should consider having the pump taken out and overhauled. Often the shaft seal begins leaking and result in water damage to the motor bearings. Bearings can be replaced, but compare labor and parts for overhaul to simply replacing the whole pump.
