Question about Zoeller M53 Mighty Mate Iron Body, Poly Base Automatic Sump Pump 1/3 HP

1 Answer

Rapid on/off switching while crock is drained below float level

It's sort of like fibrillation. When I jiggle the flost trip lever a few times it seemed ok but problem recurred several hours later. Did the same thing and it has stopped for now. Can't find record of installation. I think it is about 5 yrs. old. I have a Zoeller water powered back up installed next to the main pump as per specs.

    Hi, how is this unit powered? does it have two cords so that the float switch turns off the unit by piggyback cord?

Check the check valve it could have mud or just debris on the flap,, take it apart and clean it out see if this doesn;'t help after that you might just want to change the pump if it is in a high volume usage, area

I have a xt500c thermostat the display goes blank stay off a few days the thermostat comes back on and the unit will run than it will go off again

Sounds like you have a clogged drain. Drain is draining enough to clear the float switch, unit comes on produces water, water backs up and trips the float switch again therefore killing power to the tstat. Shop vac the drain line!

How do you manually adjust the height on the float switch lock on a pacific hydrostar submersible pump Model 93820 - 1.2 HP

you have a float switch that has a lenth of wire. If you want to Lower the water take a couple of large zip ties and rap the around the motor. dont make it to tight because now come the adjustment. You take the foat and turn in upside down and hole it at the level yu want to water to be at. Take a second zip tie and rap it around the wire going to the float. so that were the tie that is on the motor lines up with the wire as it hangs down at the point you tie the second zip tie to the first and pull them both tight.

what you have done is shorten the wire to the float so that the pump turns on sooner than if yu were to let the flost extent the wire all the way out.

Hope this works for you have fun.

How can I adjust the float?

You can't adjust the flost on those pumps... there is a magnetic switch that turns the pump on when the float gets to the top...

The only way to adjust the water level is to adjust the hieght of the whole pump...

The bucket full light stays on while it is empty. the humidity control doesn't change. the unit is not going on.

There should be a switch that is activated by a float lever that if tripped will make the bucket full light stay on, and will prevent the unit from going on.

If this light is on when the bucket is empty, maybe try to jiggle the float lever, or investigate why the switch is activated when the bucket is empty.

Good luck on this repair.

Drain in the close position the drain handle is not working

Remove the 2 screws on the drain cover in the bath tub to gain access. Drain plug should be connected to trip lever on drain cover probably using a cotter pin with ends bent to keep it on. Do not yet remove the cotter pin.

To know for sure if it is the trip lever broken, you can hold the trip lever down and tub will drain. If you let go, trip lever on cover returns to upright position and stops draining. You can also feel the spring tension stay on it when you press the trip lever down. Most likely, the drain trip lever (spring action) which is a part of the cover itself is broken.

First have ice pick, thin screwdriver, (even a large paper clip (or 2 for strength) bent straight may do) or anything small enough to go through same hole in drain assembly as cotter pin, while long enough to go across hole in bathtub to hold drain assembly up till you install new drain cover attaching it to assembly with same or new cotter pin.
Now unbend the cotter pin (sort of looks like a heavy duty metal bobby pin) ends using pliers. Using pliers pull cotter pin out while holding drain assembly so it will not fall back into tub wall.
Next secure assembly using the above ice pick or large paper clip while you take trip lever (which is the cover)
to hardware store, etc. to pick up generic tub trip lever.


There is a metal stem with a threaded rod coming up in it with a nut on it, and on the end of this is a round metal weight looking much like a very small upside down can. you will not be able to see all this unless it is neccesary to remove entire drain assembly which you can then take it to a Home Depot or Lowes type store to replace. Most can be replaced with a generic tub drain.
Now to get the assembly out once you've removed the 2 screws gently work metal stem assembly up and out at a slight angle. You may have to move nut on assembly to shorten the length in order to get it to clear the tub. IMPORTANT! If so, 1st mark the position of the nut on the threaded rod so you can put it back in same position when reinstalled before lowering assembly all the way back into tub wall.

How to install a toilet trip lever

Ok eve, Here is the concept of the workings. The "ball" is hollow, cone shaped and open on tje bottom. On its side there is a hole.
When you lift the Flapper ball, the water drains outand as it does the flapper fills with air so it won't close until the water level drops. The hole in the side bleeds out the air so the flapper will stay down once it is seated in the drain hol. Tank fills and the water pressuer og the filling water increasrs the pressure to hold the flapper seal and covering that vent hole. When you press the lever it has to be held long enough for the water lrvel to drop below the raise flapper so air can get under it or it will immediately drop because the draining water pulls it with the current. So, the adjusting chain mus be short enough to raise the flapper about 45 degreees and held till the water level drops below it. One thing that dictates the amount of time you have to hold it is the water level in the tank. It should be about 5/8 inch from the top of thr frain tube. If water level is correct the flapper will surface enough to grab air in a much shorter time. So the water level is important. Cycle it and you will see what I mean. Good Luck _Ned_
Let me know if your problem persists Eve. I have one doing the same thing . Make sure the lever is lifting the flapper straight up as possible

Level one working but not level two

Check to see if unit is running outside. Could be iced up. Float switch tripped means stopped up drain. Float switch located under unit or in front. Does your fan work on on positio. As a service tech he first thing we check is power to the trnasformer but unless you know what your doing you will do more damage. Check float switch and then call a service tech. Rusty

Wont drain!!!

Check first the drain lines and the drain pump.

If the drain pump is working, and there is no problem in there, then the problem is usually because the water level switch activated by the floating sensor is stuck.

You probably need to have the water level switch replaced.

You can find parts on websites below:

My dishwasher when switched on keeps throwing the trip switch

i had this probem and apparently there's a 'float switch' in the bottom of the machine. This switch is a safety cut off and when activated can not just stop the machine but trip the electrics in the house. the reason for it activating is when food clogs up the drainage bit water can not drain and fills up the bottom of the machine. this then activates the 'float switch' as a kind of safety cut off.
the way to sort it is to disconect the machine from the mains and drain and water. empty the clogged up food from the drain bit. then tip the machine back and a load of water will pour out (may need a load of towels for this bit or take the machine out the back and do it)
once this is done, plug it all back in and give it a try - works for my machine, good luck.
