Dishwasher overfills? I've tested the pressure switch and anti-flood device using multi-meter and both seem to be working fine. Dishwasher starts to fill and doesnt stop (only when power is turned off). Water doesn't continue to fill so I presume inlet valve is ok - must be something not telling it to turn off. But how would d/w know this and not start pump to clean? I have even manually blown into pressure switch - I hear it click but water doesn't shut off. I've looked at circuit board and can't see any obvious problems. Please help - this is driving me crazy!

There is a water level pressure switch that is your issue. Replace that or if youre lucky, clean the hose/pipe connected to the pressure switch and it could work again.

Hello

Most faults can be referred to the fact that the Anti Flood Overflow device has activated.

Modern day dishwashers like those manufactured that have a built in safety feature protecting the dishwasher against flooding. The technical term is 'Anti Flood Device'.

In the base of the dishwasher in the plinth there is a float switch. This is your 'Anti Flood Device'. In the event of your dishwasher over filling, the plinth fills with water, the float rises and actuates the switch.

Firstly, it will send a signal to the programmer device to notify there is a fault and output a message in the form of a code to some sort of display.

Secondly, the pressure switch acts as the water level indicator for the sump of the dishwasher so when the water level rises the pressure switch will activate the drain pump.

So before you consider throwing good money at new dishwasher, try doing a bit of fault finding your self and you might save yourself a ton of money.

Hi, E2 means that anti flood device has been activated. The machine has overfilled.
Check in the base (under the bit you put the dishes in) to see if it's flooded. The causes for overfilling are blockages in the metering tank, blockages in the system hoses.
Drain the water out of the base and try the machine again. If it overfills you'll need to take the machine out, do a fair bit of dismantling to get at the hoses etc. to clear the blockages.

Hi Jeffrey,

This depends what you mean by "runs". If the dishwasher continues with a wash cycle - i.e. circulating water - with the door open, the simple answer is that you have a defective door microswitch.

However, I suspect what you perceive to be the dishwasher running, is actually the drain pump running continuously. This happens when the anti-flood protection system has been activated and continues even when the door is opened. The simplest way to check is to open the door (while it's "running") and pour some water into the tub. If the water drains away immediately, this shows the drain pump is running and the anti-flood protection has been activated.

This may be due to water having leaked into the base of the dishwasher, but it could be as simple as a stuck or defective float-switch.

Please try the simple test above then post back for further assistance. If you're planning to investigate or repair this yourself, you're going to need a Torx T20 screwdriver and a multi-meter would be useful as well.

drain pump blocked and has overfilled flooding base pan and activating anti flood device tip machine to the left to remove water and consult handbook on how to clean pump outlet.

See if the float in the front corner inside the unit moves up and down freely and makes a "clicking" sound when moved. If there is a clicking noise, the float switch is probably okay. The switch can be tested with a volt/ohm meter by removing the lower access panel to get to the switch. Some units have an actual water level pressure switch attached to the pump housing instead of a float and switch. These switches can plug up with soap residue causing a no fill or overfill condition.

The problem is more likely the water inlet valve. These valves go bad frequently for a variety of reasons. It is not worth the risk of a valve failure and possible flood to take apart and clean an inlet valve. Replacement is the best solution. In most conditions, the inlet valve will need to be replaced every 4-6 years.

I managed to clean the filter inside the dishwasher and drain a little residual water. I then re-plugged in the appliance and the anti-flood device seemed to reset and I have n't had any problems since.

most bosch have the inlet valve at the end of the fill pipe and it has an anti-flood device.
try turning off the water, take off the fill pipe then reconnect it and see if this works.
taking off the fill pipe resets the anti-flood device

Is there water in the drip pan? My asko developed a leaky inlet solenoid, which would fill the drip pan eventually causing a failure. If the water evaporated, the washer would run. Normally, there should be no water in the drip pan.
