The Bosch dishwasher has a logic system for the event of a leak. there is a float in the pan under the dishwasher. If any debris gets under the float and it cannot return to normal position. The dishwasher will not fill and only drain. The solution is to take off the toe kick plate and look with a flashlight on the left side. There is a depression and a styrofoam float, a narrow vacuum can be used to vacuum any debris from under the float. If there is no debris then the switch is stuck and requires replacement about $30.00 for the part but requires removal and partial disassembly of the dishwasher. I bet the problem is debris under the float. I hope this helps.

Also...make sure you visit the Bosch dishwasher recall website as this model is under the recall with a faulty controller which may cause a fire! Check your model under http://microsites.boschappliances.com/safetyrecall/dishwasher/
then call 800.856.9226 to setup a recall repair appointment. We just found out about this recall and was never notified by Bosch even though we registered our unit after we purchased it...talk about poor customer service! Hope this helps!

I have a lg dishwasher and it ran for an hour and a half and then displayed E1 on it. Then, it would not stop running and wouldnt even turn off so i had to turn it off by the breaker. any solutions?

(1) The water inlet valve is an electrically-controlled valve that opens to allow water to enter the dishwasher. Depending on the model, the valve stays open either for a set length of time or until the dishwasher has enough water. However, if the water inlet valve doesn't shut off after the dishwasher has enough water, the dishwasher will overflow. If water drips into the dishwasher when the door is open, or if water collects at the bottom of the dishwasher while it is not use, you may need to replace the water inlet valve.
(2) The float switch actuates in order to prevent the dishwasher from overflowing. If the float switch is defective or stuck, it might not stop the dishwasher from overflowing. If the float switch is defective, replace it.
One would need the model number of your machine.

Hi... I just bought Electrolux Dishwasher ESF2433W. When i first time turn it on, light at "Normal" button keep on flashing with beeping sound. After checking the trouble shooting manual, it actually refer...

E4 Overflow

Sometimes during trasport it is possible that styrofoam float mechanicaly activated overflow microswitch. So, you should check complitely overflow system.

At any time, if overflow micro-switch act and keep for longer than 2 seconds, the E4 would occur. When E4 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes (if the model with the pressure switch (83/63),drain pump would run till the pressure switch reset and continue draining for 60 seconds.) and all the other components will be stopped immediately. At the same time, the buzzer will alarm for 30 seconds and error 4 will be shown. Note: Priority level of E4 is the highest. E4 operation is valid after other error operations have done. When E4 operation has done, all the others are invalid.

A KD12DSS-2 KELVINATOR DISHWASHER WITH FAULTY ERROR 4 CODE

Hi.

Error 4 is internal leakage (overflow).

when this happens often the dishwasher starts with the pump running continuously.

Switch off the power from main circuit breaker, drain the inside of the appliance and clean the drain filter in the bottom panel of the tub. If problem persists, check the drain hose at the back. Ensure that it is not kinked, and that height is as from installation manual.

If that does not work, then the machine is faulty. Repair is done removing the kickplate at the base of the appliance, checking for water leak in there. Disconnecting pump hose and removing debris, testing the overflow switch by running a cycle with its contacts jumped. The inlet valve must also be checked to ensure that it is not leaking.

Turn off power and remove water from inside the appliance. Usually that is enough to sort out the problem.

Regards.

Water in bottom of dishwasher, how do i drain & reset?

Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

Danby Dishwasher stuck in drain cycle after wrong soap use

There might be water in the overflow sensor. I unloaded the dishwasher and lifted the front so the dishwasher rested on its back. There's a narrow gray tube that runs down from the bottom right of the door. The tube runs into a white piece of plastic with some wires coming out of it. There is a rubber plug that covers a nipple on the plastic. Pull the rubber plug off. Mine was quite tight. Tip the dishwasher back onto its casters to drain the water from the overflow. Check to see if the dishwasher functions normally, then put the rubber plug back on.

Miele G575

This sounds like the overflow trip switch has been activated. Some time back I had this problem with a Miele G664. The service man undid 4 screws on the door and removed front panel and found water in the drip tray, He then checked the pipes, outlet pipe had a pice of plastic bread tag stuck in it , this was slowing down the time it took to empty the water and the next fill made it overflow and switch off the dishwasher. He cleaned out the chanel on the overflow that was full of dust and fluff checked the levels to make sure the dishwasher was sitting true. Closed it all up and ran the dishwasher. Perfect!

Bill $160. It did take him the best part of an hour and I live a long way out of town.

F9 FAULT

one of two options: 1. Door lock circuit, Check wiring and test operation of door lock switch 2. Overflow Condition If the Overflow contact on the pressure switch is Closed for more than 60 seconds and Overflow condition will occur. In an Overflow condition, the Door will remain locked, and the Drain Pump will run constantly, even if PAUSE/CANCEL is pressed twice and the Display is cleared. god luck Unplug the unit to service. Check the drain hose and make sure it is not plugged or inked. Check Wire Harness connectors to the Drain Pump, Pressure Switch,and Central Control Unit (CCU) Check/Clean Drain Pump Filter of foreign objects Check for Drain Pump Failure Check the Inlet Valve for proper shut off Check the Pressure switch for proper operation
