Check that your supply faucet is open, Check if there is a screen in the supply line, these can become blocked due to scale deposits from the mains. If there is no screen check that the inlet solenoid valve has not got blocked. If none of the above help, check that there is power getting to the solenoid valve when the machine is supposed to be on the fill cycle. If no power is getting to the valve, the timer might be faulty. (You can try hand filling the machine and see if it goes through a cycle, at least up to the rinse stage, this will tell you if the timer control is working).

Hi,

Here is a tip that will help you to find out why water will not come into the dishwasher...

Hi

Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter. Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn't overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn't working properly, the drain pump isn't working correctly, or possibly there is a plumbing problem in your home's drain lines. First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. If you have checked the drain hose and can't locate the problem, then it is an issue with the drain pump of the dishwasher. Please rate the solution if the issue is resolved or post a comment for further assistance.

Thanks

Hi,
Here is a tip the will elaborate on your problem more, but the bottom line is that you need to replace that fill valve...

Check for a clogged drain (e.g.: via drain hose), or a water pump malfunction due to foreign obstruction (e.g.: glass, etc).

Note: If you changed a food waste disposer (kitchen sink area) and did not remove "plug" from disposer for dishwasher drain hose (assuming dishwasher drain hose connected to food waste disposer), then water cannot drain from dishwasher.

This does sound like a problem with the "anti-flood" device that does detect water (leak / spill) at the base of the washer. This device is a protection device that consists of a polystirene float and a micro swithch. Once a water leak or spill is detected it automatically puts the washer in pump out mode and switches the inlet water off. You need to determine if a leak exists that has caused the float to trigger the micro switch and clear the water / leak. This should put the washer back to normal.

The water level detector pipe could be obstructed / blocked. This thin plastic pipe is at the bottom of the washer and as it fills to the correct level of water the pressure in the pipe activates a water level switch in the washer. Sometimes the air pressure pipe becomes blocked / obstructed or the contacts of the pressure switch become burnt. You can disconnect the pipe and blow through it and the pressure switch is normally factory set and does not need adjusting. Replace it if necessary.

Following is a complete trouble shoot for your dishwasher.

Most probably a float valve or alignment of the door interlock switch.


Start with the simple things and work your way from there. You will be amazed how many people call a plumber who flips a breaker or simply clears a stuck float valve (for $80 minimal fee).

If no lights are coming on.

First check the breaker to the machine.

If you have an exposed power source to the machine such as a plug or junction box open the box and check the wiring is intact and not rusted etc. Take care here and shut the breaker off first.

No go so far?

Check if your float valve is jammed.

The valve is a safety feature to stop the machine from over filling. If anything gets under the valve it will jam open and stop the machine.
Look inside the machine on the floor will be a small float valve. Looks like a small upside down cup. Lift it and clear anything from underneath.

Not the float valve either?

Check the door interlock latch.

Much like a washing machine a dishwasher will only operate with the door closed (or when it thinks it is closed!). There is a metal tab that engages a switch in the door. This is the same switch that activates as you operate the handle to open the door. If it is misaligned it will not signal the machine that the door is closed and the machine will not operate.

You can check this by overriding the locking tab. Put a screwdriver in the door latch and press the switch. You should see the lights come on and power flow to the machine.

Note: if the machine is in run mode you will get water spraying.

To fix this problem bend the tab to properly engage the switch. Or if necessary loosen the screws retaining the switch and move it to correctly align with the tab.

Not it?

OK now you are into electronics.

First is quite simple. Some units have an internal fuse to protect the control panel. Check that first. Take your time and take care. Turn the breaker off.

The control panel is screwed in place. Remove the screws and gently remove the control panel. Take care not to have parts of the door latch fall out or springs drop out etc. On newer units it is very simple as it is just a circuit board. Look for the fuse and check that it is OK. Replace if necessary with correctly rated thermal fuse.

=======================================================

Do you have water in the bottom of the machine?

Power is there, lights are one, seems to want to work. Water will come in but will not drain.

A small amount around the drain is normal for some machines. This is held to keep the pump primed in some units. However it should not fill the bottom of the unit. You know what it normally looked like so it if is full then you probably have a jammed float valve as above or a clog in the drain.

Drain clog.

Remove the cover from the drain in the bottom of the dishwasher. They usually lift out or have a few screws holding them down. Simple to figure out just take your time and try not to force anything. Look for a clog and clear if necessary.

Your drain can run either direct to the drain under the sink or to the disposal unit if you have one. The drain can clog at either point.

Check by disconnecting the drain line from the dishwasher where if connects to the sink or disposal unit. Look for a clog and clear if necessary.

Water exits the machine via the drain pump. If it is not operating the machine will not drain. It will fill usually to the point where the float valve lifts and does its job by stopping the machine before if floods your house.
If you have water in the machine to the point the float valve is lifted then drain it out first.

Your machine should be running now. Lights will come on and it will run again to the point where if fills with water and trips the float valve again. If so then check the pump and timer (see also timer below).

Remove the units as per below.

If your pump is belt driven check he belt (very few have belts).

If direct drive switch the unit on and let if run to the drain cycle. If the pump does not come on check for voltage at the pump during the drain cycle. If you have voltage replace the pump. If not it is the timer that is faulty (see below).

---------------------------------------------------------------------------------------------------

OK now your are getting to some deeper issues. Not necessarily hard but only go here if the simple things are OK.

If you are not getting water into the unit but you have lights on and you hear clicking and the timer runs and things are trying to work then we know you have power and the timer is running.

No water coming to the unit.

Make sure nobody shut the supply line off. There should be a tap under the sink on the water supply line to the unit.

Turn the unit on an listen at the base for a click as the water supply solenoid (electric switch) opens. No click?

Check the solenoid. Remove the machine from under the counter. There will be screws holding it to the underside of the counter. You may have to lower the legs to get it out. They turn with a wrench to lower.

Under the unit where the water supply line comes in is a solenoid switch it opens to allow the water to enter the machine. Water comes in under household pressure (it is not pumped in by the unit). Chances are it is faulty. Replace it as it can't be serviced.

Still no luck?

The unit is guided by a timer. The timer tells the machine what to do and for how long. If it fails the unit will stop or jam in one cycle. If you have a physical switch the you turn to select the type of wash cycle check it. If you are all touch control then replace the whole board or machine.

To check the switch open the control panel above and use a voltage tester to see if you have current at each cycle point. Cleaning sometimes helps if not replace.

Hope this helps you. Please rate this tip for me.

you must change the module control .that will solve the problem. if this helps please give me a 4 thumbs up post. thanks

the unit is going into drain mode. check your hose for leaks. when water leks in the base of the unit the float switch is activated and the unit will stay in drain mode until the water is removed. check float by removing side panel and look into bottom base for water.

Im a bosch tech and there is a access that you would need a torc srewdriver open plastic door in the bottom of the dishwasher.

check if the water valve is opened, also you can check the check the solenoid connections and the probe. also you can put a bucket or two of water directly in the dish washer to check if the probe and ather parts is ok.

The readings appear ok to me. The circuit that controls the element and any fuse in that circuit have to be suspected now.

E3 usually indicates the heater element has failed perhaps it has now also blown a fuse?

E3 usually means the heater element has failed. From the title of tyhe post it seems you know that already.

E3 means longer heating time. Usually this indicates the heater element has failed.

you could be correct as the proceedure for all dishwashers when started is a pumping phase to make sure no excess water is still in unit.. when finished water then flows in..
