Zanussi Dishwasher DW929 will not take in water

If you can see water flowing down the overflow channel to the pan at the bottom of your Bosch dishwasher while it is running, this indicates that there may be a problem with the dishwasher's float switch or water inlet valve.
The float switch is a small device located at the bottom of the dishwasher's tub that is designed to detect the water level inside the dishwasher. If the water level rises too high, the float switch will shut off the water inlet valve to prevent the dishwasher from overflowing. If the float switch is not functioning properly, it may allow water to continue to flow into the dishwasher, resulting in water flowing down the overflow channel to the pan at the bottom.
Another possible cause of this issue could be a faulty water inlet valve. The water inlet valve is responsible for regulating the flow of water into the dishwasher. If the valve is stuck open or is not functioning properly, it may allow water to continue to flow into the dishwasher, resulting in water flowing down the overflow channel to the pan at the bottom.
To resolve this issue, you may need to have a professional technician inspect and repair your Bosch dishwasher. They can test the float switch and water inlet valve to determine the cause of the problem and replace any faulty components as needed.

The OE or Overflow Error code.
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.

The dishwasher does not heat up the water. The water should be hot coming into the dishwasher, check your hot water supply source, whether it be the hot water tank or be sure the water inlet for the dishwasher is not connected to the cold water line

Your dishwasher uses your hot water to wash the dishes.
Attach your hot water to both the sink and dishwasher at that (hot water) inlet.
Run the hot water in your sink until it is very hot, then turn on your dishwasher.

Hi


When the Dishwasher is not filling in, you'll need to check for the water inlet valve, the filter screen and the float switch/assembly. Also check for the float assembly inside the dishwasher. When water is filling your dishwasher, a float rises along with it. As the float reaches a certain threshold level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages.
If these are fine then it's due to Water Inlet Valve. Use a multimeter and check for the continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. Hope this helps... Please post back for any further assistance.

The slight buzz is coming from the water inlet valve solinoid. It's OK.

But check whether water is getting into the inlet tube of the washer. Check the filter at the rear of the dish washer body wher the inlet tube from your water tap is connected.

Hi there,

Well first of all you can check the Water-inlet valve
Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it. When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need replace it.
After then you can check the Drain valve,  that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.
Please post comments if you need more help or information..............

Good Luck!!

Thanks

Sounds like you have a leaking inlet valve. The best option is to replace it with a new one. It does have overfill protection on it but this may not work if its leaking.

Check first the filters on the inlet water line (both sides). Then, if problem still exist - check that the inlet water valve works(it is an electromagnet valve, located at the pipe's entrance to the machine)). If it doesn't work, test that it get power. In case it get power and doesn't work - You can easily open the valve and clean it (from scale or other dirt). Be aware you should disconnect the power cable from machine before doing it !!!! Check as well for valve's coil resistance. In case you have no resistance measurement - you should replace it for a new one. Good luck
