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.

I would suggest to check the information by clicking here if you are planning to DIY.

Water inlet solenoid valve faulty. Check this is voltage to valve when water should be flowing. Replace valve if there is voltage present.

Paul,If this dishwasher has just been installed or there has been some plumbing work done in the sink cabinet. Please check the shut off valve for the water going to the dishwasher. it is connected to the hot water pipe in side on the sink cabinet. if the shut off valve is already turned all the way to the right it is in the closed position. This would mean the water is off. turn the valve to the left to turn the water on.This is very common after new counter tops are installed.Please also check water line going to the dishwasher to be sure it is not pinched
Hope this helps

Hi

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.

Check water inlet valve

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.


How to test a dishwasher water inlet valve.
How to replace a dishwasher water inlet valve.

first make sure the valve to your dishwasher is on, if it already is, turn off the valve[ usualy under your closest sink] and make sure the line is'nt kinked. if not it's most likely the pump in the unit itself.

there may be something under the "float" causing the unit to think it is already full of water. the float is a round cone looking device in the front corner. make sure nothing is under it or holding it "up".
the other thing is the valve may have an open coil and then it would need to be replaced.

definitely no delay in fill, i would recheck the water line make sure not kinked, also check wires leading to the valve for good contact to valve body

If your dishwasher is cleaning poorly, check these:

Water-inlet valve
Internal filters
Drain valve
Spray arms
Water temperature
Detergent cup
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.
