My Bosch works very well.But when you idol it for several days, there will be a lot of water, if you don't clean up,soon or late got overflowed


If the dishwasher is filling to overflow level when not in use, you need to replace the water inlet valve/solenoid assembly. The valve is not closing fully allowing water to seep into the washer.

If you have a check valve for the water supply to the dishwasher, I'd suggest closing the check valve while the washer is not in use until the inlet valve has been replaced. If you don't have a check valve, if you leave the power switched on, the washer will automatically pump out when it reaches overflow level. The anti-flood protection system will stop the dishwasher overflowing as long as the power is on. Closing the check valve is by far the best option!

The inlet valve/solenoid is located behind the toe-kick below the door and is relatively easy to replace yourself. The only tools required are a Torx T20 screwdriver for removing the toe-kick and the valve.

If you are confident that you can undertake this repair yourself and have the tools, I've listed the part/supplier details and fitting instructions below. If you would prefer to call a service technician, make sure you aren't charged more than $30-35 and no more than an hour for labor.

Please note: This part relates to the Bosch SHX45M05UC/xx. If you do not have this model, verify the correct part number for your model before ordering.

Part number: 607335
Description: Water inlet valve (sometimes called water inlet or valve access)

This part is used on all versions of SHX45M05UC/xx, so it doesn't matter if the 'xx' on your model is 01, 02, 06, 12, etc.


Bosch - $28.10 plus shipping (in stock)
Sears Parts Direct - $24.49 + shipping (on backorder)

There is an option on this page to check part availability at local stores.

Appliance Part Pros - $29.21 + shipping (in stock)

(APP use their own part numbering. This part is listed as AP4070550)

Fitting instructions:
1. Switch off the power at the breaker and close the water supply check valve
2. Clear as much water from the sump as possible - a turkey baster works well for this
3. Remove the two Torx T20 screws from the toe-kick then tilt the toe kick out to remove it
4. Remove the base insulation (if fitted)
5. Disconnect the water supply line from the inlet valve
6. Make sure the sump inlet hose is clear of the inlet valve
7. Disconnect the wires from the water valve - make note of where to re-attach first!
8. Remove the two Torx T20 screws from the inlet valve
9. Pull out the inlet valve and disconnect the hose

A small amount of water will drain from the hose when you disconnect it (assuming you drained the sump first) so have something ready to catch the water if possible.

That's it. Refitting is the exact reverse of the above. This is a relatively simple repair, but it's a good idea to take digital photos as you go along so you can refer back to them when re-fitting parts.

Hope this helps. If you have any questions or need assistance should you decide to replace the valve yourself, please let me know.

Bosch exxcel auto option - Have not run it for a couple of months. Turnit on al all it does is pump out


The usual reason for this is that water hes leaked into the bottom of your dishwasher under the washing compartment. This has caused the float to rise and trip the switch which activates the Aqua-Stop / anti-flood protection system. This also closes the solenoid (water control valve) to stop water entering this dishwasher. You may already have had a small leak before you stopped using it.

The only way to check this is to remove the washer from under the counter (disconnect power and water supply first) and tilt it backwards about 15-20 degrees. Water should run on to the floor from under the washer so I suggest putting some old towels down first. Once the water has been drained from under the washer, you can use it again, but it's not advisable if you have a leak and this really needs to be investigated.

If there is no water from under the washer, you may have a faulty float switch or possibly a faulty control module.

Hope this helps.

Float switch fault
Water in the drip pan. Changeover contact of overflow float switc

1. Remove the water from the drip pan (e.g., with an absorbent cloth).
Upon opening the appliance and removing all water, there should be no
smudges, smears or traces of deposits.(rust, calcium, detergent, or salt?).
2. Check all hoses, connections and threaded unions for leaks.
If the leak source has not yet been detected, check the following areas
in the toekick and the drip pan for wear and tear:
�� Connection between the circulation pump and the sump
�� Axial face seal of the circulation pump
�� Connection between the drain pump and the sump
�� Connection between the salt container and the water intake
�� Connection between the water intake and the cabinet side wall
�� Overflow (e.g., excess foam formation)
�� Water level between the overflows (�� seating of the lower door seal?)
�� Connection between the cabinet and the salt container
�� Non-return valve in the sump (�� water running back from the drain hose?

My asko 1585 overflow switch is activated. I fixed the drain problem now how do I stop the pump from running and the lights from flashing?

Hi drlebo, You can go about that one of two way's. 1) wait a day or two until the water in the overflow basin evaporates enough to satisfy the "overfill float switch" or...2) remove the toe panel and soak up the water in the basin with a sponge or towel, shop vacuum etc. Insuring the power is off first of course. Once that has been accomplished it is simply a matter of pushing any of the keypad functions for 3-5 seconds and the unit should "reset". Hope that help's. Thanks for visiting "fixya" for your repair inquiries. Let me know if I can assist you further and please take a moment to rate the info I provided here for you. Thanks again & good luck.

The clean water fill will not shut off and water overflows from the dishwasher onto the floor. We had to turn off the water supply to the dishwasher to get it to stop.

Fill valve is shot , new one required


Does it still run when you remove the power if so the above applies

If it shuts off then the problem sits with the pressure switch

Bosch SMS4012GB dishwasher. Refused to fill. Found tray full of water in base of unit. Mopped up water about 2 litres. Machine works but lower reservoir on the side of the machine with float switch...

An electric switch activated by air pressure. This device detects air pressure exerted on it through a flexible tube connecting it to part of a water tub.
When activated, this switch then opens an electrical circuit stopping further filling of water into the machine.. May also be called a PRESSURE SWITCH. if not activated definately it will cause overflow.

Check the wire harness to the pressure switch. or tap your float switch with finger tips may be it get stacked. if nothin happen replace the pressure switch.
Rate my solution if useful.

My dishlex dishwasher overflows

The only part that physically allows water to enter a dishwasher (upon receiving power from the control) is the inlet water-valve. I would test the inlet water-valve located directly where you in-coming water line is connected to.

Shut-off power to the dishwasher and remove the 2 prong connection to the water-valve solenoid (small, black, batter size). Test the solenoid for continuity; if bad, replace the entire inlet water-valve (cost about $20)

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.
