SOURCE: Bunn Tiger espresso milk pump blocked

Hello. Is the pump working, just not actually pumping? are you cleaning it with the recommended chemicals and frequency they suggest? it may require more often than is being performed. If you ran out of detergent and haven't been cleaning, that is part of the problem. How to resolve the current problem may require removing the pump and taking it apart fully to clean it properly. Depending on the pump, make sure if you take it apart, you pay full attention to all the parts as you disassemble it. Putting it back together wrong could ruin the pump, and I am sure they are not cheap. If you are not comfortable with this contact your local servicer to do this. You can order your chemicals from www.bunnomatic.com, of call them for a supplier. It is cheaper to clean it more often, than replace a pump.

Hope that helped, and thank you.

SOURCE: My Hamilton Beach 40729 will not brew! The motor

This unit does not use the pump to generate steam, so if the pump is bad (motor works but the pump it drives does not transfer water) you will get steam but no water through the head to the portafilter.

The unit is not user serviceable and at $68 to buy a new one, it is for the most part, disposable.

The pumps on this unit do not like to be run dry as they rely on water as a lubricant. Without water in the reservoir, the pump may fail in a short running time.

SOURCE: I have a Gaggia Evolution expresso maker about 8

Try this, under the grouphead, there is a screw and screen, remove those, and check screen to see if it is clogged, when screen is removed press button to brew, if water flows freely then problem is at the screen, if no water flows, then it is on the inside of the machine. You will have to run a descale cycle to clear out machine. Check the folling pic for the screen location.2722dbe.jpg

SOURCE: Lights on, motor running, does not do single/double shots

There is a tiny plastic one-way valve in the brass tube on the pump under the top cover that get calcified and stuck when not in use. I used a toothpick to get it out after disassembling the pump and its hoses. Slowly and carefully lay out your parts to reassemble the springs and washers correctly.

Hi, Like any washer if you smell something burning and a humming from the motor I suggest you take out any cloths in it and try turning the inside basket clockwise to see if it turns freely and if it does then the motor is defiantly shot but if it won't turn freely then either something is jammed between the inner and outer tub or the transmission if it has one is bad or the bearing housing is bad so try and disconnect the belt from the motor and see if the motor runs and if it does then follow from the motor to the tub and see what is frozen .

Good Luck

Hayward Pump motor, hums but won't start. If I turn the shaft it will keep running but once I turn if off it will not run until I do the same thing again. I have replaced the capacitor but still the s


1 or 2 capacitors on this motor?
Sometimes there are two...
One is a "Start" capacitor and if a 2nd one, that one is a "Run" capacitor.

If only 1 capacitor and you have replaced it... if not a faulty capacitor, then your windings are shot?

When I test a motor with this symptom, I will use the "Clock Face" method of checking for "Dead Spots" on the winding/stator:
Once you have removed the shaft cap on the back of the motor, I presume you have done this since that is only way to turn the shaft manually to get it to run in the manner you described. Place a small mark (1/4" long?) on the outside perimeter of the shaft, say at the 12:00 position. See picture attached...
Then flip switch, does it start or hum?
Then rotate shaft until your mark is now at the 1:00 position. Flip power switch, running or humming?
Do this at all clock positions as you turn/rotate shaft until you reach 12:00 once more. If the pump hums at all clock positions completely dead motor or bad capacitor. If a dead spot is at only one clock position, then absolutely, bad motor - either rebuild or replace.
Coincidentally the motor may stop each time on a dead spot, where the motor won't start due to a fried portion of the stator/winding/armature, only a major repair fixes this. The purpose of the test is to place the position of the stator in a different position in relation to the windings. If humming all the way around, then possibly a bad capacitor, because it is not starting in any position. If it starts say at all positions except 4:00 and 9:00 then motor is bad.

Good luck

When the fan or A/C control is turn on a hum can be heard but nothing happens. I went up and the fan initially wouldn't turn. I got it to spin, but still only a hum when the switch is turned on. Seems...


With the unit off put a drop of 3 and 1 oil on the fan shaft where it goes in to the motor and spin the blade by hand a few times to work the oil in the motor. If the shaft is dirty in the area clean it first with alcohl on a rag to get the grime off it then oil the shaft.

Th end of the shaft that come from the motor is worn out, and won't hold the belt well. How do I change it?


Hello,

Thanks for the clarification. I have never seen this problem previously in a Kirby. I wonder if the belt keeps sliding off because it's been stretched out? After about 1-2 years, the belts on the Kirby will stretch out to a point where there can possibly slide off the motor shaft. Have you tried just replacing the belt on the unit first?

If you're sure that it's not the belt that may be stretched out, and you'd like to replace the motor shaft, you certainly may do this. The only problem with this is the motor shaft is not sold by itself as a separate part. The only way to purchase this motor shaft is to purchase the entire fan assembly, which includes a new fan, and the hardware necessary on the fan assembly.

Here's a parts diagram that shows you the motor shaft is sold only in a completely assembly:
http://lib.store.yahoo.net/lib/vacuumcleanerbacgs/kirby-generation-parts-diagram.pdf

If you haven't already purchased the motor shaft, here's a direct link to the motor shaft and fan assembly on our website:
Kirby Generation Fan Assembly With Motor Shaft and Hardware

In terms of installing it, we've actually recorded a video repair on how to replace the fan assembly, which involves removing the motor shaft in order to get the fan off. Since you have to purchase the fan assembly anyways in order get the motor shaft, you may want to go ahead and replace your fan assembly at this time also. Even though your fan may not be broken, on Kirby's the fans can become coated with dirt and fine dust, which can sometimes lead to the Kirby exhausting a bad smell. If you'd rather not replace the fan, you may remove the motor shaft without disassembling the entire machine, you'll just need to secure the fan somehow so that the fan doesn't spin while you're using a nail to turn the motor shaft off.

Anyways, here's the video repair that we recorded. I hope that this helps you.

My model 137.21990 bench top drill press, the electric motor will turn if I take the belt off the pulley but when I slip the belt back on the spindle the motor stops turning and just hums!! I shut it off...


The motor is not necessarily shot. It may be that the motor can't handle the load. Even with the pulley and belt assembled your running at virtually "no load". The problem may be that when you attach the belt it pulls the motor "out of true verticle" which in turn causes the shaft to sieze inside the motor housing. Try making sure the motor is square and aligned exactly verticle and it is secured firmly to the base plate.

Washer will not agatate at all, just makes a humming sound win on


HI. the internal components that make up the agitator should be inspected for damage.

The agitator is fastened to the agitator shaft and its movement is driven either by splines or a simple clutch assembly. The splines are usually plastic or rubber nubs on a cylinder that fits over the agitator shaft. If the nubs wear down, the shaft will not turn properly or it will turn weakly. If the agitator is moving in only one direction, the likely cause is the clutch assembly. The clutch has dogs that depress and pop up with each turn. If those dogs are worn, they will not engage properly and the agitator will turn only in one direction. Another issue that might cause this disruption is the Motor coupler.

Washers with a direct drive motor have a motor coupler instead of a belt. The motor coupler consists of three plastic disks (or tri-stars) with interlocking tabs. Those tabs can wear and break which results in slippage. The slippage causes little or no power to be transferred to the transmission. A worn motor coupling can result in weak or no movement of the agitator and spin basket. Inspecting the motor couplers requires removing the motor, which is fairly easy to do.

Remove the cabinet. Locate the motor. The pump is mounted to one side of the motor. You do not have to remove the hoses from the pump unless they prevent you from moving the pump out of your way. If you must remove the hoses, label where they connect first. To disconnect the hoses, pinch the wire clamps with pliers (or loosen the screw) and slide the clamp farther up the hose. Slide the hose off of the pump port.

There are two clips that secure the pump housing to the motor. Use a screwdriver to pry up the clips and remove the cover. Next, slide off the pump to reveal the motor. Disconnect the wiring harness from the motor, do not pull on the wires themselves. The motor typically is secured with retaining clips and bolts. Remove the bolts and use a screwdriver to pry up the clips (if present). Remove the motor.

Mounted on the shaft of the back of the motor you will find the motor coupler. Separate the three disks and inspect them for damage. If you find cracks or excessive wear, replace the coupler.

**(((If the motor couple is in good condition, replace the agitator components and clutch assembly as well.)))

The washer hums and blows the breaker


It sounds like a motor problem to me. The transmission in not elecrtical but it could be locked up. Try turning the tub by hand and see if it turns. if not take the motor out (unplug first) and try to turn the transmission. But with the "hot smell" more and likely the motor is shot. This is all depending on your type and modle of machine you have. Let me know.

Jetted bath tub has stopped working - motor hums, will not run


The shaft on the motor should spin freely as should the impeller when attached to the pump. If there is drag on either, replace the pump and motor assembly. I have worked on jetted tubs for the past 5 years, I have seen seized pumps more than once.

Lg dishwasher lds 5811st E1 error code


Hi Chaz,

The impeller breaks on the motor shaft. The motor still turns, but the impeller doesn't, so it doesn't pump water. Because the machine senses there is no water pressure from the pump, it shuts down & displays E1 (it thinks there's a water leak, due to no pressure)
Unfortunately the motor/impeller is only available as a complete assembly

Hope this helps
