I took my Dell wireless mouse apart to clean the wheel. The spring fell out. I don't know where it goes back ( I didn't see where it fell from). I put it back together without the spring and now...

i beliece it is very fiddly to put that certain spring back in cus it is hard to see where they go back, my advice is to go to a local PC store and get them to use the right tools to place it back in for you.

Front loading washer, kenmore 417.42052100 won't completely drain and leaves a tub full of water. Has been getting worse over the last week and now won't drain at all. Took off front panel to try...

The drain filter/coin trap is blocked or the pump is no longer working. The filter/trap is located inside the big black hose that runs from the bottom of the tub to the pump and hence the name tub-to-pump hose. Clean the filter and inspect the pump impeller for damage or restriction.

Disconnect power then remove the screws attaching the bottom front panel to the cabinet then pull the panel down and off. Once the panel is off, you can now loosen the clamps securing the tub-to-pump hose to the bottom of the tub and the pump's inlet then take the hose out and clean the filter/trap.

You should find foreign objects such as coins, toothpicks, hairpins and the likes blocking the filter. Clear the filter from the foreign objects and inspect the pump impeller by turning it with your finger. The impeller may be restricted or damaged resulting in the water not being pumped out properly or none at all. Replace the pump if the impeller is broken or restricted and doesn't turn freely or if the pump is no longer operational. You can tell the pump is no longer operational if all are clean and the impeller is in good shape and turning freely. Reassemble the machine by following the steps above in reverse order.

When installing the filter in the coin trap, the top ring of the filter MUST be seated in the 3rd convolution from the bottom.

How does the spring go back on the impeller?

You will need a new seal if the spring has come apart from the rubber. Almost any time you remove the impeller you should change the seal. The half of the seal that has the ceramic goes into the seal plate rubber first. The half with the spring slides on to the impeller shaft with the rubber first so the graphite faces the ceramic. Both pieces should have a small amount of teflon grease applied first to be sure they go on smooth.

A coin fell into the basket and rolled into the gap at the edge of the wash plate. I took the plate out but the coin was not there. It must have fallen into the larger slots beneath the wash plates. If I...

The coin will not drain out nor be fed back into the tub by the recirculation pump but it will block the filter or eventually block the impeller of the drain pump and break it. You'll then experience a draining problem and need to replace the drain pump.

What you have to do is remove the basket to get the coin out then take the opportunity to clean the filter vanes. The coin is most probably still in the filter.

Tape the lid to the top of the washer then disconnect power to the washer.

The top of the washer is held to the front of the cabinet by two locks located about six-and-a-half inches away from the outer edges of the washer. Use a putty knife blade or similar tool to press and unlock the top locks.

Insert the blade of a putty knife into the seam between the top of the washer and the cabinet at the given distance from the outer edges of the washer. Press the locks then lift the top of the washer.

Remove the impeller (wash plate) cap by inserting the blade of a flat-bladed screwdriver or similar tool into the slot in the impeller cap, and then pry the cap off.

Remove the 7/16" hex-head bolt from the impeller (wash plate), then lift and remove the impeller from the basket.

Pull the recirculation hose off the tub ring by compressing the spring clamp holding it in place. Remove the tub ring by prying and unsnapping its tabs from the tub.

Lift the basket out of the washer to access and clean the filter. Remove the two screws holding the filter to the tub. Take the filter off and clean it.

Reinstall the filter, the basket, and the wash plate. Secure the wash plate with the 7/16" hex-head bolt then snap the impeller cap in.

Put the tub ring in place aligning the tabs then snap the tabs back into position. Reinsert the recirculation hose into the tub ring and secure it with the spring clamp. Push and lock down the top of the washer to the cabinet.

In case the coin is no longer in the tub or in the filter, turn off the water supply to the washer. Disconnect the fill hoses from the rear the washer and remove the end of the drain hose from the laundry tub or stand pipe.

Place padding or cushion on the floor fronting the washer, and then carefully lay the washer on its front panel to access the drain pump at the bottom of the washer.

With the washer facing down and you facing its bottom, the drain pump is on the left while on the right is the recirculation pump. You can actually see the drain hose connected to the drain pump.

Using a pair of pliers, compress the spring clamps holding the drain pump inlet and outlet hoses. Move the clamps away from the pump then remove the hoses.

Remove the three 5/16" hex-head drain pump mounting screws. Open the wire cover on the pump then disconnect the wires from the terminals of the pump, and then remove the pump from the washer.

Check the pump impeller for any debris and clean it. Reinstall the pump after cleaning and secure it with the three 5/16" mounting screws. Reinsert the inlet and outlet hoses then secure it with the spring clamps. Make sure the tab on the outlet hose connector fits into the slot in the outlet hose.

Reconnect the wires to the pump terminals then close the wire cover.

Nursery pro water pump nph 1200 i stopped it last autumn... i try to retart and and i ear the sound, but the pump dont start to spin... i unmount the pump and casing... do we have to put oil ou grease on...

First, the reason you are having this issue is that you let the pump dry out during to off season. I know it would not seem this simple but the seals in all underwater pumps must stay wet once they have been in water or the metal shaft parts rust and prevent the pump from spinning. So going forward, get a old 5 gallon bucket, put the pump in it, and fill with water over the off season. I too leaned this the hard way.

Now for the pumps you have. With some careful disassembly, you might be able to save them. Please make sure you have unplugged the pump! Turn the pump over and remove the 6 screws holding the bottom screen and impeller on. The cover is held on by a gasket so carefully pry the over off. If you are really lucky, you will find a rock binding the pump. I know, not that easy.

Next you will see 4 screws deeper in the housing. Remove them and seperate the bottom half of the housing from the motor. Now you can see and clearly work on the removing the impeller and berring seals off the shaft.

This is where you need to be very careful to remember how all the parts go back together. You will find metal washers, rubber seals and ceramic seals. They will all seperate if you are very careful. Pry very carefully on the rubber and ceramic seals. THEY WILL BREAK and then you are done. Also, there is a spring which is not under much tension but if you are not careful, some of the parts will spring off when you get them free. If this happens, you will ask yourself, why did I not look closer at how it went together.

Maybe try the CSI approach. Take digial pictures at each step so you can have a reference.

From here, you are on your own. Clean all the rust off the parts. 600 grit sand paper will be needed to clean the motor shaft - it will be rusty and pitted. Just be careful, just take the high spots off.

So finally, here is the disclosure. Of course there must be one. I have saved my pump twice before I figured out the water in the bucket trick. When I reassemble my pump parts, I coat them in a clear silicon grease used for bicycle parts. Non of this is anything official and probably not what the company would agree to. But before you throw away another pump, it is alwasy worth a try to fix it.

We all really need to find ways to fix things before throwing them away.

Good Luck!

Put back togather

Well I did it. It's not exactly easy to describe. I accidently took mine apart trying to clean the roller ball and out popped the 2 springs. I sort of put it back together in "reverse". In other words, I put it together without the scroll device and then looked through the hole. By doing this, I figured it out -- when you know it's simple but to describe it without pictures is almost impossible. Mine works fine now but I don't know how to help you.
