Sounds the float switch has gone bad. If it is a mercury type with a tether line to the pump grab it and shake it like a paint can and it may start working again but even if it does I would replace it. If it is a rod type you can try pulling up on the switch arm but it probably needs replaced also.

My sump pump wont kick off. There is no water in the sump and the float is fine, but the motor won't shut off. I unplugged the pump as to not burn up the motor, and thinking it may reset itself, but when...


Hello, the pump motor is controlled by the float switch. If your motor is running constantly even when you move the float switch around, then I would say that either the switch is shorted internally, or the wires going to the switch are shorted, thusly causing the motor to run. Is the float on a separate adapter to the pump, or is it wired into the pump?

F2 lights indicated. pup wont stop when machine turned on. no water in cabinet. course fine filter removed. yellow plg removed to check for obstructions. none found.


Hello,

Welcome to FixYa.

Based on your description " f2 lights indicated. pup wont stop when machine turned on. no water in cabinet. course fine filter removed. yellow plg removed to check for obstructions. none found." the good news...It is likely nothing very serious, but the "reset" requires some investigation on your part.

The "drain stuck cycle" or "F2" ( I presume you mean drain pump running constantly ) are directly related with overfill scenarios for Asko dishwashers of this era.
This is meaning the control is indicating an overfill has been detected. Whether the unit has actually overfilled or not remains to be seen.

In the event it has, the outlet/drain pump motor is automatically turned on via either the pressure switch or a float in the base if sensing an overfill and removing water from inside the dishwasher will do nothing to resolve this error, but you can...

**before proceeding turn the dishwasher power off via the home breaker panel, or unplug it from the wall if that is possible...most are hard wired to the home electrical...safety first**

The first thing to do is remove the toe panel/kick plate and inspect the base for water. If water is present, with the aid of a sponge, towels, or a wet-dry shop vacuum, absorb the water from the base.

If the unit works fine after resetting the power/breaker it can likely be chalked up to a drain back-up or obstruction in the drain hose or pump.

If not, there are a couple of other possibilities that I'd focus on.

**again insure power to the unit is off**

The first is the float and subsequently, float switch. If you've removed the service panel at the bottom, or toe plate, you need to locate the float and it's switch. It will be located directly behind where your main electrical junction is...

i.e.

macmarkus_4.jpg
Once you've located the float behind the main connection plate, you should see something like this image below,

i.e.


macmarkus_6.jpg
With the aid of a long screwdriver or if you can reach it, move the float up and down and listen closely for the switch to "click", indicating it is indeed functioning.

Restore power again, and see if this resolves the issue, if not try this next...

The pressure switch too can cause the drain/outlet pump to run constantly ( and usually all the lights to flash or "F2"...depending on the era and model of the Asko ).
As I was saying the pressure switch is the component which controls the normal fill level and the overfill detection...pre float activation. The float is primarily the last ditch safety to notify the user in the event of a overflow, back-flow, or leak underneath the unit to service or call for service to the unit.

It too is located under the machine and is mounted to the sump well assembly as shown, the large arrow indicates the switch while the small is the hose.

i.e.

macmarkus_7.jpg
The issue is possibly just the hose going to the switch is clogged with debris such as dirt, detergent buildup etc and will be remedied by blowing it out.

The best way to do this is to remove this hose at the switch in the location indicated above, be very careful as to not break the hose off with the part of the switch inside, they can be delicate.

I typically work it loose with a tiny screw driver gently working it away from the switch. Once removed, pour a small amount of hot water, white vinegar or "CLR" through the sump from within the tub...or you can try blowing it through with "lung power".

The other end of the hose is located at the back of the sump well and is quite vulnerable to blockages over time due to detergents, dirt, and such.

This is the location...do not break this or you will need to replace the entire sump well...no fun.

Large arrow is pointing back to pressure switch, small indicates connection to sump well, sorry for the poor quality...it's hard to get in there with a camera phone, ha ha !

i.e.


macmarkus_8.jpg
That's almost the extent of the possible causes of this error. Of course it could be the pressure switch has failed, the float switch has failed or ultimately the control has failed, but not likely.

Hope this helps move you forward, or even better resolves the issue altogether. Let me know of course, I will help you move further if necessary.

Good luck.

Regards,

Macmarkus :)

Sump pump will not stop. Float is moving freely with nothing in the way. I moved float fully downward and pump does not stop till I unplug it. Please help! Email is kwakjoe@comcast.net. Thanks!


the pump should not shut off until you move the float fully upward. You should feel the switch actually click when the float is raised. If it doesn't make a clicking noise then something is obstructing the float from being able to rise to its full height.

The entire float ARM, ie the part that is connected to the motor, has to move up and down with the float or it will not work.

Water does not drain out


Hi and welcome to FixYa, I am Kelly.

There is always just a minimal amount of water in the bottom of a dishwasher so that the pump seal does not dry out causing water to run through the pump motor. Usually though it is not visible yet is is possible.

Excess water in the bottom of the tub post cycle are a sign of draining problems however this is a list of what it could be.

1. A partially clogged drain
2. The timer motor is not functioning properly
3. A broken or worn pump impeller
4. Clogged wash arm holes.

Here is what you need to do:

Check your entire drain system. Start at the final outlet and work your way backward to the motor pump connection on the dishwasher.

Suspected areas are.

a. The sink connection outlet is clogged (this can be inside a garbage disposal.

b. The air-gap is clogged in the very top part of the air-gap (Usually located on the back of the sink and is around 3 inches tall) Remove the cover, unscrew the top nut and check under the horse shoe bend inside the plastic top for obstructions. Clean as needed)

c. There is debris on top of the the motor pump housing blocking the inlet drain. (This would be inside the housing of the lower wash arm on the very bottom)

d. The motor pump outlet drain port is partially blocked. (only accessable from the motor pump exit hole after drain hose removal.)

A partially blocked inlet tub drain to the motor pump would also explain why the lower part of the dishes are not getting clean. Additionally you would have spotted dishes post cycle.

When the drain is partially blocked some models use the float level switch in the tub to control the advancement of the timer. If the water does not drain the motor pump continues to run and run and the cycle does not advance until the tub is drained and the float switch senses same. i.e extended cycle
Check under the float assy for debris.

One more thing to check is the lower wash arm holes for debris or obstructions. If the wash arm is retaining water it can drip out after a drain cycle and cause the puddling you noticed.

Thanks for using FixYa.

Bosch dishwasher has water in bottom after cycle is complete


Hi

Kindly check for the following :

Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.

Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.

Please contact for any further clarifications.

A Fixya Rating would be appreciated if.

Thanks
