Question about Equator 20 in. PLS600 Free-Standing Dishwasher

Erestanding Equator PLS600 Overflows

What can cause these dishwashers to overflow? I know of two reasons. Are there more?

This dishwasher certainly could never be called a pot scrubber, but it ran satisfactorily for two years. Then it began over flowing.

The cause the first time was the filler shut off. The filler shut off mechanism is a pressure switch at the end of a long tube. When the water rises to a sufficient level it is driven into the tube raising the pressure and closing a switch and causing a relay to shut the fill valve. the tube had been clogged with built up debris and cleaning out the tube caused it to resume working.

The second time the clean out fix did not work. The problem this time seemed to be the door. There is no door seal at all on the dishwasher. Instead, flanges on the sides of the door opening fit loosely into deep recesses on the door sides and a flange on the door bottom fits in a recess at the bottom front of the door opening. Water splashes on the door, runs down and collects in the recess at the bottom, flows through that channel to the sides where it runs back into the sump.
The channel at the bottom had become clogged and the water could not drain easily back into the sump.
It built up until it overflowed. Cleaning it out seemed to fix the problem.

It worked for several loads before it overflowed again. This time it does not seem to be either of the first two problems.

Is there any other possible cause of an overflow?

Thanks.

    I had recently blown out the tube leading to the pressure switch, but when I did not get any response to this question, I decided to try really cleaning the tube well. I disassembled it completely and cleaned the lower part with a doubled coat hanger wire. The dishwasher is working now. I'm keeping my fingers crossed.

    I still wonder if there is any other possible cause of water overflowing.

    BTW Sorry about fouling up the spelling of Free-standing. They need an editing option for those of us who do not always proofread..

May be this time the drain hose has been clogged or the drain hose is at a higher level than the unit or may be the drain pump has stopped functioning.

Bosch dishwasher overflows thru front door


Is there an opening on the right hand side of the inside of the machine?I had this happen and it turned out it was because this hole (opening) needs to be clear during operation. Try running it with nothing on the right hand side and if it doesn't overflow, that's the problem. You can only put short stuff in the back bottom rack on that side.

Equator PLS600 spray arm will not move.


Problem solved. Removed spray arm assy including nut (attached to body). Manually moved propeller inside water inlet. This freed it up enough to get her working again. Apparent cause was enough debris in chamber to cause it to seize. Note that this fix was preceded by the famous WikiFix of filling chamber with baking soda then topping it off with white vinegar, left overnight. Also note that the above manual movement of the propeller was done with the machine on (not recommended) at the point in the cycle where the spray arm should have been operating.

Water overflows from dishwasher.


The most common cause of a Sears Kenmore dishwasher over flowing is a fail "float" switch that detects when the water has reached the proper level.

Give the spray arm a spin to make sure it rotates. It should spin freely. If not, remove plastic spray arm clip, flip it over, replace it, and try again. Make sure holes in the spray arm are clear of debris. Spray arm must be clean for it to spin. If spray arm does spin freely, remove spray arm clip, spray arm and the post assy (the thing the spray arm attaches to). Try your WikiFix again. This time add baking soda to the hole the post assy came from. Top it off with white vinegar. Leave it overnight. In the morning, stick your finger down the hole where the spray arm assy sat. You should feel a plastic thing. This is a propeller attached to the recirculation pump. You need to free it up. Get that thing moving with your pinky or a chopstick or whatever. Try the machine without the spray arm. You should get water blasting up from the hole. Reassemble the spray arm.
