MAH3000AWW Trips 20Amp Breaker at rinse cycle

I have a MAH3000AWW washer and when it hits either of the two rinse cycles it trips the breaker, 20 amp. If I re-set the breaker and turn the control knob, even quickly, past either of the two rinse cycles (either regular or delay) on the knob it will instantly trip the breaker. When it first did it, at the first rinse cycle, there was a smell of something burning (electrical) . Motor problem??

    I have the exact same problem on the exact same washer model. I kept trying to restart to the point that the start switch finally failed (big spark and smoke) so I called the repair man. His only recommendation was to replace the start switch for $180. When asked to guarantee that this would fix the problem, he couldn't but reassured me that it was most likely bad start switch. Well I replaced the switch myself for $20 and 15 minutes of labor, and the breaker still tripped.

Had the same problem a while back. Check the "wax motors" that control the softener and bleach dispensers. One of mine had shorted out and grounded every time the cycle hit the softener cycle. disconnecting the wax motor solved the problem

The motor is known to have bad windings. Do a search for "Neptune Washer will not start" Also just inside the control panel where the start/stop sw is should be a paper folded with the diagnostics test and schematic. It is tucked under the pressure sw attached to the back. If not there then search "Maytag Neptune motor phase test" There is also a Service Manual FREE at Goetlieh's site.

Admiral washer. Did load of laundry, breaker tripped, and is still full of water. Reset breaker, and hear a small click after I pull knob to restart washer. Breaker trips. No leak, and outlet is good


The washer tripped the breaker once and OR after the breaker was reset it ran additional loads with no problem then it tripped the breaker again.

Intermittent problems are always difficult to diagnose because the problem usually doesn't occur when you're making the checks.

If the washer ran additional loads the problem will not be an electrical short with one of the washer parts. If the lid switch had a short it wouldn't run the additional loads.

You don't say if the additional loads used the same cycle as previously. A timer can have an internal short that might trip the breaker in heavy duty cycle but not the permanent press cycle.

If you have access to a clamp on amp meter, see the image below, then you can check the amp draw of the washer. The washer normally will draw about 10-15 amps at start up and about 5-8 amps while running. The house breaker for you washer should be rated at 20 amps.

If the washer is running and drawing less than 20 amps and the breaker trips then if can be a weak house breaker.

Mid cycle the washer is most likely draining or spinning and if the bearing or pump locks up then the washer may draw additional amps to try to start and trip the breaker.

The key to this problem is what the amp draw of the washer is when the house breaker trips.

To narrow this problem down, there are three places that could be causing the ( outlet) GFCI to trip, a malfunction in the washing machine, a problem with the downstream wiring (aka load side of the GFCI-other items connected on same circuit), or the GFCI outlet itself. If there isn't anything downstream, then plugging the washing machine into another GFCI outlet, or simply swapping out the outlet for a known good GFCI outlet, will identify if the outlet itself is faulty.
If the outlet trips when the washing machine isn't running and isn't even plugged in, then there's a fault in the wiring on the load side of the GFCI outlet.
If the issue is neither of the above, then running the washing machine and monitoring to see which step is occurring when the trip happens will isolate what part of the washing machine may be leaking current to a ground. It could be a certain water level, a motor being engaged, a transition step in the controller, etc
Beware some techs believe that most Washing machines or any other motor should not be on a GFCI! Should be a dedicated single receptacle. If there are other outlets on the washer GFCI, replace that GFCI with a single receptacle and put the GFCI on the next jump in order to protect other outlets.

Another item to check is ur lid switch which may have gotten moister inside and created a short_ or broken open and the rubber seal dried out over time, and the switch assembly will be exposed. water can splash onto the assembly, somehow causing the GFCI to trip. In any event, if you are having trouble with your washing machine stopping mid-cycle for any reason, test and replacing the lid switchis probably a worthwhile idea, as it is cheap and easy to replace.
By the way my advice is free cuz God is good!

Spin cycle trips house circuit breaker on my GE top loading washer


Hello,

The very likely reason the breaker trips only on spin is because the tub bearing is locked up on the washer since it is locked up its causing way excessive friction at the motor which causes the breaker to trip.Can you rotate the tub by hand or does it seem really hard to rotate by hand indicating that the tub is ceased up due to the tub bearing??

Washer keeps blowing fuses


Do you mean the houses circuit breaker? If so, WHEN in the cycle does it blow the circuit breaker? WHEN it trips will tell you what to look at. I.E. If the circuit breaker trips during the fill cycle then it would be the walter inlet valve or the timer in the control panel; if it trips as soon as it is in the agitator cycle - then the motor or transmission; if it trips in the spin cycle - then the drain pump or transmission or control panel.

LG Washer trips dedicated breaker


That to me seems like an electrical problem. Every now and again you can get a bad GFCI receptacle that will constantly keep tripping. I would also see that the GFCI is properly sized for the circuit. It needs to be a 20 AMP circuit (just dedicated to the washer) and a 20AMP GFCI receptacle. The way to tell is the 1 of the three prongs of the 20AMP GFCI will be in the shape of a "T" while a 15 AMP will have 2 straight prongs and the ground prong. Hope this ws helpful, don't go spilling any money into your washer without getting that fixed first, because it doesn't seem like a washer problem.

Washer fills but trips breaker when trying to start wash cycle. Does the same with rinse and spin cycles and when plugged into another circuit


Hi there
OK thank for writing to fix ya. Sounds like your breaker can't support your washer so you need to replace you breaker where it can handle you washer. just go up another 30amps on your breaker and try that. let me know how that goes.
Best regards Richard

Why does my washing machine trip the electric


run the machine, after it trips, unplug and carefully touch the motor,it may have a bad capacitor, or dry bearings causing it to draw excessive current,if these 2 things are not it, then look for a bare wire that may be touching case during this part of the cycle,and if you can get an "Amprobe" it reads current and check machines current draw during the start to trip current
