Did you have this problem before replacing the solenoid coil or it start after ? In case it started after solenoid coil replacement, its look like you did something wrong while assembling it back. Disconnect Dishwasher power cable and close water tap - remove the selenoide coil, clean the valve from scale or other dirt and check that you placed all parts back properly (spring,gasket...). Good luck !!

SOURCE: Bosch SHU4300 Water Fill Issue.

Similar problem for us turned out to be water accumulating in the tray which set off the float switch.  I vacuumed the water out and function returned to normal.  However, we are now facing a repairman's assertion the clay in our well clogged the water inlet systems necessitating $285 in repair parts and labor.

SOURCE: My bosch dishwasher does not fill with water (although it drains)

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

SOURCE: Bosch SHU9925UC Dishwasher Stuck in Initial Drain Cycle

OK Bosch Dw is the fix if your SHX dishwasher is stuck on the drain cycle. This may save you a couple hundred listen up. There is a tendency for the very small float switch to STICK in the ON position, which will cause the drain motor to continuously run......and DISallow any other function to work. DISCONNECT POWER. Did I mention to disconnect power? Take off the front base cover....2 torx screws. Remove the other 2 torx screws in the metal clips that fasten the top of the DW to the underside of your countertop. NOW...carefull slide your DW out. You may have to disconnect your water and elec supply if you do not have enough slack to pull it out. Once the DW is out of the cabinet, remove the shiny metal cover on the LEFT side by removing a single torx screw. You will now see a small plastic assembly with a red plastic piece that moves up and down as it rides on a small red styrofoam float. This up and down movement engages a small white plastic switch visible with 3 wires coming out of it. You can carefully UNSNAP this switch out of its mount, and pull the 3 wire plug off of it. THere is a small square blue plastic tab that is supposed to easily slide in and out of the switch. If it is stuck IN, you can sometimes tap the switch and the blue tab will pop out, which is what it is supposed to do without tapping it. You can carefully with a knife blade separate the case on this switch and note the way it comes apart. Clean out any micro debris out of the small channels that the blue tab ride up and down in. Then set it in the channel while holding up the small switch tab that rides on it and see if it slides up and down without sticking! I like to take a piece of wax paper and rub in on the channel and blue tap to provide some lube for the switch to slide easily on. Now, put the switch back on and manually move the red plastic assembly up and down while you are watching the blue tab. The tab should ride up and down with the red assy. If not, buy a new switch. Google the # on the switch and order one. If the tab slides up and down, put things together in reverse order and give it a try. Hope it works for you. This should take you an hour give or take. Take the $200 you just saved and have a night out on me. even though these German Appliances have a good name because of past reliability, the american tendency to value engineer them with plastic parts to reduce costs and increase profit.........just cost you an hour of your time. Will we ever learn.? ......if it ain't broke, value engineer it until it only lasts through the warranty period so you can then collect service and parts blood money from your fellow american.

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.

Bosch dishwasher SHE46C06UC won't fill with water

Check water inlet. Check for kinks in hose. Check the inline strainer in the fill solenoid. You say it makes an attempt to fill, is this because you can hear water trickling? If so I would suggest get to g the fill solenoid replaced as it may be blocked or not opening fully

Ge diswasher won't fill with water

When the program is switched on if there is no water flow despite the fact that the inlet flow is good, then the inlet valve is defective. it can be a failed valve if there is no action and if the flow is low then it can be a clogged valve. Remove, back flush and reset, if not replace, provided there is power to the valve.

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,

Water is not flowing into Bosch diswasher


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.

Bosch smu4096ud /14 dishwasher wont fill with water

Find out where the water is being stopped. Firstly at the wall. Then maybe at the solenoid (depending on the model) and then just trace the water line until you find out where it's being stopped.
Also I would recommend you run some nickel safe ice machine cleaner through the system to get rid of the 'white junk'.

Whirlpool APDW2 dishwasher not filling with water

The most common problem when a dishwasher is not filling with water is a failed water inlet valve. It is a solenoid valve that sits directly behind where the hot water hose connects to the dishwasher.

Bosch Diswasher SGS4012GB/13

First check the machine is getting electricity (and the problem isn't a blown fuse!)

A very likely cause is that the solenoid on the inlet valve has gone. Rarer possibilities to consider are water turned off at the mains, a blocked inlet strainer (where the inlet hose mates with the valve), or a problem with the programme controller.

The inlet valve is near the top of the machine, and is the thing the hose from your outside water supply screws into. The solenoid is the electrical bit that clips onto the top of the valve body.

I suggest you go out to your local appliance spares shop and buy a replacement solenoid for not much, fit it and see what happens. It is possible to do a series of tests to confirm first that really is the problem - but with the solenoids being cheap, I'm inclined to suggest not messing around with test gear, water and mains electricity.

When replacing the solenoid, make really sure the machine is unplugged from the electricity supply.

Usually best to take the top panel off to gain access (try taking the trim across the back of the top panel off, then sliding the panel off backwards).

Disconnect the cables from the old solenoid. Prise it off the valve body. Snap the new one on in its place and refit the cables (it doesn't really matter which way round they go, but one way will probable look neater than the other).
