No pressure Pump reassembly. I purchased a new pump and installed it. Got machine back together and I'm not getting any pressure. What would be the signs if I don't have the shaft key in properly? Or any other suggestions? Water comes out of nozzle with pressure for a quick second then no pressure, just water. This is a brand new pump so was curious if I installed it wrong. Wondering before taking it apart again.

its a matter of removing components out of the way until you can get all the pump bolts out. clean the block surface before you install the new pump. Reverse procedure to reassemble the engine.

I will take a shot at this question, only because I had a similar problem this past spring. You probably have everything hooked up correctly, the pump, the shaft key, and everything else the way it should be. If the unit sat for a while, or a long period of time ,it may have built up some rust , at the nozzle end. I will assume that your pump comes on and no water comes out of nozzle. If this is so remove nozzle and look through the small hole in nozzle. If you don't see light this is most likely your problem. Take a small piece of wire, or a pin and push it through. I had a nozzle clog on me this way. I didn't think this could happen till I started to diagnose down the line. Please get back to me with your results. GOOD LUCK FREIND.

somtimes the problem is not in the pump try to blow air to the shrink that feed the water out from the pump maybe its dirty and that you do before running to buy a new pump.

I recently purchased a refurbished EM-200 and it did not work and leaked water all over the place right out of the box. Without doing anything water leaked out of the bottom of the machine. When I tried to run the machine you can hear the pump but no water ever came out and after a few seconds it quite and the lights would start flashing and beeping.

The mechanical engineer in me just had to solve the problem. I unscrewed and removed the bottom plastic cover (3 screws) where the power card goes into the machine and found the problem. The water from the reservoir feeds into a white plastic priming pump. This priming pump is assembled in two halves and one half has four plastic clips that hold the pump together. In between the two halves is a rubber o-ring. Well, one of the clips was not secured and I could see part of the o-ring protruding. This is an obvious source of leakage. Either the pump was not properly assembled or it snapped out of place during shipping.
I unscrew the two screws that hold the priming pump in place, leaving the hoses attached, and carefully pulled the two pieces apart. Note how the magnetic impeller is installed and reassemble the same way. Use a small amount of vegetable oil to lubricate the o-ring and reinstall in the same place. Reassemble the to two halves, making sure the o-ring doesn't protrude, then snap the two halve together tightly. Screw the primer pump back into place then screw the bottom plastic cover back into place.

After this fix the machine no longer leaked and it brewed a nice espresso. Everyhing seams to work find now.

1. You only should have one check valve; the one in the water is best, remove the other if you can.
2. Make sure there are no leaks in any of the piping between the water and the pump inlet.
3. Take the pump apart, thoroughly clean the new seal, the two halves of the pump that go under the metal band, the inside of the metal band.
4. Lubricate the new seal, the outer sides of the pump halves where the metal band squeezes together, the inside of the metal band where it contacts the halves and even the screw on the tightening device using petroleum jelly (Vaseline) or equal. Make sure the pump literature does not recommend against whatever you use.
5. Reassemble.
6. Fill the pump with water, open the discharge on top of the pump if possible and prime.
Normally, a pump, even with a long run will prime in 5 minutes or less.

Write back.

Scott it sounds like a problem occurred during the reassembly of the pump..missing an o-ring? gasket out of alignment? blockage somewhere on pressure side of the hoses? a problem with the ram?

Disconnect the high pressure hose to the ram and place it in a container to capture the fluid...activate the pump switch and see what you get...should see a good steady supply of hydraulic fluid.

After that you will have to check the ram for proper operation.

Hi Adam just found your posting,Do you still need help?If you do reply back and I will help you rectify this fault.Looking forward to your reply.

Check the drain hose and clear it from any debris that might be blocking the water from draining out completely. If the drain hose is clear of debris, check and clean the pump. Disconnect the machine from the power outlet before servicing for safety purposes.

Remove the rear access panel to access the pump and disconnect the wiring harness from the terminals of the drain pump and the pressure switch.

Loosen the clamps holding the drain hose and the tub hose to the pump assembly. It is a good idea to spread a towel under the pump before loosening the clamps.

Remove the hoses and rotate the pump assembly counterclockwise to release the pump assembly support legs from the keyed slot in the base of the washer. Remove the pump assembly from the washer.

Clear the pump impeller from any debris that might be causing it to work improperly. Clean the tub and the drain hose.

Reassemble the pump, the hoses, and reconnect the wires to the terminals of the pressure switch and the drain pump. Reinstall the rear access panel and run the machine.

Replace the pump (part #25001052) if water still do not drain out completely.

Remove the plastic bag covering the pressure switch. Press in the locking tabs on the back of the pressure switch and pivot the pressure switch off the pump bracket.

Grasp the pressure switch and lift the nipple of the pressure switch from the pump cap.

Install the pressure switch into the new pump assembly in reverse of the steps above.

Remove the rear access panel to check the source of the leak. The drain pump is most probably broken or the sump hose is damaged or detached from the tub.

Drain Pump Removal/Replacement Procedure (Maytag Neptune MAH5500B)

1. Safety first. Unplug the machine.
2. Remove the hose clamps and hoses from the pump.
3. Disconnect the wiring harness from the pump and the pressure switch terminals.
4. Rotate the pump assembly counterclockwise and remove it from the base of the washer.
5. Remove the plastic bag covering the pressure switch.
6. Press in the locking tabs on the back of the pressure switch and pivot the pressure switch off the pump bracket.
7. Grasp the pressure switch and lift the nipple off the pump cap.
8. Install the pressure switch on the new pump in reverse order of the removal steps.
   
9. Install the new pump in reverse of the removal steps above.
