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.

make sure you clean the sprayers out real good,if theres debris on the end nozzles they dont spin around too good,also pull out the little service plug that protects debris from getting in the impeller.
i found a little chunk of wood in there! im still not sure how wood ended up in the dishwasher!

So if I fixed it you want me to give that info to you for free but otherwise you want to charge me for an answer?

Sounds like you need a new water inlet valve. It's not shutting off completely, so water slowly enters the machine even while it isn't running.

Many new supply lines have a safety valve built in to prevent flooding in case of major malfuction. Floodsaver is one of the brands. They can be identified by a small silver cylinder at the water valve end under your sink. I have found that then valves can close under certain conditions other than a malfunction. Try turning off the supply valve and then very slowly, reopen it. Sometimes, I have had to turn off the water supply valve, disconnect the line to relieve the pressure, reattach and SLOWLY turn the water back on. If this fails, next try the diagnostic procedures here:

best of luck!

Replace the water fill valve, it's leaking.

You need the check the water level switch which is located on the diaphram of the water fill assembly. This is located on the laft side of your machine behind the metal panel. if this switch sticks it will not allow water into the machine

It is the inlet valve, some are located inside the appliance, some mounted in the back panel. Occationaly some have the valve at the end of the hose in a box. The price for repair the first one cheapest the last most expensive. regards Appliance Doctor
