SOURCE: Bosch SHU 4000 series dishwasher; Water keeps on filling

Follow-up: I was able to fix the problem on Bosch model # SHU 4002UC. Purchased water inlet valve (part number 425458) from Sears Parts Center. I required the Sears unit number from the original invoice as Sears computer system apparently cannot identify the Bosch model number. The valve is as described by meyerjr above; however it is located at the bottom front of the machine so could be replaced (not so easily) without removing the machine. Cost of part was $30.50 Cdn including tax.

Bosch dishwasher doesn't work. water not coming

Hi Gilgol, The link below is a Bosh Dishwasher list of error codes, I believe your error code is E3....CHEERS..
Bosch Dishwasher Error Code E3
Fault Condition: Not filling with water
Repair or Check: If the water supply cut-off valve on the dishwasher is completely open but the dishwasher will not fill with water then shut off the water supply and unplug the dishwasher. Remove the water fill line and check to see if the water inlet screen valve is plugged up. If so then replace the water valve. Cleaning the screen can make the issue worse so always replace if the screen is clogged. The valve can get stuck open from gunk and therefore flood or overfill.

Dishwasher will not fill with water when turned on

Hi and welcome to FixYa, I am Kelly
The following steps require using electrical power. You assume all responsibility / risk for any mis-fortunes cause by working on this dishwasher with power applied.

The first step will require using a meter on the water valve solenoid teminals.
- Remove all power.
- Remove the lower toe / kick panel(s).
- Locate the main water supply line and follow that to the inlet water valve.
- Slide the connector(s) off of the solenoid and read resistance on meter scale R x 1 or R x 10. You should read a low resistance. If you do not read any resistance the inlet water valve has failed.
If you do read resistance you must check switch the meter to AC voltage and apply power and read for AC voltage on the teminals of the wire harness.
- Start a reular wash cycle to where the unit should be filing with water.
it SHOULD read 120 VAC.
If you have no power at the connector teminals
- Check the float switch plastic FLOAT. If the float is stuck in the UP position due to food particulate on the FLOAT stem you willnot have power to the inlet water valve solenoid.
If you have power to inlet water valve solenoid and it is buzzing / humming but you get no water there is debris in the main water supply line. You wil have to shut off the water supply and clean out the inlet of the water valve.

The inlet water valve replaement part is here:
Detailed View

This is what the float looks like:

This is the level switch assembly:

This is the actual Float switch: (3 terminal) POWER to the inlet water valve solenoid comes from this switch.

Check for s stuck float... and that the level switch is actuated as the float id lifed gently up and down. If you do not hear a micro-switch click the switch is bad. If the float is hard to move... clean it as best you can so that it moves freely up and down.

One of the above is causing your problem.

Thanks for choosing FixYa,

Bosch dishwasher does not fill with water


When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills 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 the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check 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. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.

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.

My bosch dishwasher is not filling up with water. Where is the inlet filter?


Welcome to FixYa.

Based on your description, " my bosch dishwasher is not filling up with water. Where is the inlet filter? "... and to answer your question, the issue is likely with the inlet/water valve.

**To remedy this you will need to replace the valve, not surprising for Bosch unfortunately**

This is what to look for..i.e.


As long as your model number is indeed SHU8805 series, this info below will be accurate.

Original part is # 425458. It usually retails for about $20 - $30USD at places such as "" "" to name a couple.

**Before attempting to repair the unit please turn off the power and the water supply to the first**

If you remove the lower kick plate/toe panel, you will see the inlet valve to your left...



Replacing it or to check for debris in the filter/screen at the inlet is pretty straight forward. Here`s how...

1) undo the water line. ( here you can visually inspect the screen in the valve...if nothing noted, you'll likely need to replace it as follows )

2) Remove the two #20 torx screws fastening it in place.


3) the feed tube to the machine at the back of the valve and swap it with the new one.


Once the new one is in you should be good to go.

Let me know if you need any further assistance, otherwise good luck.

Thanks for visiting FixYa.

Letter F appears on screen, and dishwasher does not start. Sounds like pump runs for a bit then stops. Door is closed. What is wrong?.


Error code F indicates that dishwasher control has detected a fault with dishwasher filling. This is due to faulty water inlet valve. Please check for clogged water inlet valve. Water inlet valve part#35

Hello there:
i will post this solution in 2 separate post due to the length of it ok
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 to completely replace it. Dishwasher Water Inlet Valve Replacement

Be sure to read and understand any instructions that come with the new water inlet valve.

ools required:

Adjustable wrench



Step 1. Disconnect the dishwasher from its power source.

Note: Dishwashers are usually wired directly to the home's electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.

There is no water getting to the dishwasher. Nothing has changed with the water line. Looks like there is a problem with the dishwasher. (Bosch Brand)

Hello, your problem is going to be with the inlet valve. Remove the panel at the front bottom of the dish washer, turn the water and power off. You will see the inlet valve normally on the left side underneath your dishwasher (sometimes on right) connected to the water supply. Remove the water supply hose/pipe and then remove the wire harness from the valve. Now you can remove the valve from the machine. Just inside the inlet there should be a screen...check this for debris. If debris found clean out and reassemble, If no debris replace the valve and then reassemble. If you have any other questions please feel free to comment again. Good Luck!!! Mike

Bosch SHU 4000 series dishwasher; Water keeps on filling

The inlet valve will be at the dishwasher end of the (hot) water inlet line. On this dishwasher I ~believe~ the inlet valve is near the rear of the unit. That means that you will need to pull the dishwasher out to get to it. Remove power from the dishwasher as soon as you can before messing with the unit.
Just past the connection of the supply hose and the connection on the dishwasher, there will be the valve (a solenoid valve with two wires coming out of it.) That is the little beast that has most likely failed.
Good Luck!
