Bosch shu9925 At the start of the cycle, the washer is in pump mode. It remains that way. No water flows into the washer.. It just continues to pump. We checked the drain, some debris and checked to see how the pump was working, it is fine. Any suggestions?

Check the following.
1. The drain hose has to be discharging at a high enough point to prevent water flowing back into the machine.
2. Make sure your drain hose is not twisted or kinked.
3 . Make sure your drain line is not blocked push a flexible hose down it to dislodge any fat/debris
4.If your drain line discharges into a shared drain with another appliance i.e. garbage disposal make sure it is not blocked.
5. You may have a blockage at the inlet to the pump which would slow down the pumping rate,
Since you mentioned the mushroom shaped float allowing the washer to empty this may be defective.

Hope this helps.

Bosch Dishwasher Does Not Drain

When I start a new cycle, I first hear the pump run to empty out all remaining water, and after that I hear the motor run for the regular washing cycle, but there is no water in the dishwasher. After a few minutes, the cycle stops, and the washer claims the dishes are 'clean'. When I try starting a new cycle over and over again, about one in 20 times, the cycle will run normally with water. But then the next time, the problem starts all over again. Once a cycle starts correctly, everything works fine, including the rinsing.

the unit will try to complete the last command it was engage in before it went in the overfill safety mode. you must perform a cancel drain cycle to reset unit to default setting. Remember the drain cycle is 2 min and must be completed to reset main control. however if it went into a overfill status you have a leak and it generally comes from the pressure chamber on the lefthand side of unit where the water enters tub

Hello Gerard,

This is an overfill 'fault' generally caused by one of the following:

1. Faulty or incorrectly installed flow-meter
2. An airlock in the fill chamber
3. Faulty float switch (less likely)

There are some simple checks you can do to determine the cause of the fault and hopefully solve the problem without replacing any parts - no tools required at this point.

First, open the door, pull out the lower basket and locate the float. This is the 'mushroom' in the base of the washing compartment:


With the washer empty of water, make sure the float is fully lowered. There should be a gap of 2-3mm between the float and the base of the washer and you should be able to lift it about half an inch / 12-15mm. When you lift it, it should fall when you let go. If it's raised when the washer is empty, it should not rise again on its own when pushed down.

If the float seems to be working correctly, the controller is receiving erroneous signals from the flow-meter that the washer is full or overfilled. This causes the washer to pump out - then resume the fill cycle because the water level is too low to start the wash. If this is caused by an air-lock, there is a simple trick to clear the air-lock and, therefore, the fault.

1. Start a wash cycle and keep you finger ready on the power switch on the control panel.
2. As soon as you hear the pump start during the fill cycle, interrupt the cycle by pressing the power switch to the off position
3. Wait for about 10 seconds, then switch the power on again.

The machine should resume filling rather than pumping out. Keep your finger ready on the power switch and repeat steps 2 and 3 until the washer is filled and the washing cycle starts. If you can get the washer to run a cycle using this trick, you may not need to do anything else, but you may need to repeat the procedure described above at the start of the next few cycles.

If the washer does not resume filling and continues pumping when you switch the power on again or you have to repeat the procedure above at the start of every wash cycle before it will run, you will need to check the flow-meter and, most likely, replace it.

I'm happy to provide step-by-step assistance with checking and replacing the flow-meter if required, but please check the float and try the simple trick above first, then let me know if you need further assistance.

Hope this helps.

Its possible you have a blocked drain closer to the tub. Try tilting the machine to access underneath the machine and locate the drain pump. Then have a basin read to catch any water and remove the hose that goes from the pump to the drum and check for anything that may restrict water flow, possibly a sock. Hope this helps.

Yes and no. The neptunes have always had a bad problem with that. As long as the clothes aren't soaking wet after the spin cycle you should be fine.

check the pump clean out. sounds like something is jammed in the pump

it sounds like you have something obstructing the pump. does the machine eventually empty? or does it remain with water in it. you need to remove the hose that leads from the tub to the pump and clear any debris. if you continue to run with debris in the pump you could burn out the pump motor

humming noise suggests a foreign object in the pump. crack open filter and drain water into a shallow tray. repeat till empty. remove filter completely and clean it. check if something stuck in pump impellor. this should be visible by looking into the filter hole
