I have checked the water inlet supply - I have read other posts that say check inlet valve - how do you do that? I have also read about a cut off switch on a float? I cannot see anything like that on my machine. Any help would be greatly appreciated, but please rmember you are writing to a novice.

Hi Gilgol, The link below is a Bosh Dishwasher list of error codes, I believe your error code is E3....CHEERS.. http://removeandreplace.com/2015/10/09/bosch-dishwasher-error-codes-how-to-clear-what-to-check/ 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.
Parts Required: Water inlet valve Bosch Water Inlet Valve Assembly for Dishwasher
Cut water supply off to frig disconnect water supply line to frig water inlet valve turn water back on to make sure you are getting good water supplied to water inlet valve some times water cut off gets stopped up. If you are getting good water flow to water inlet valve then check to make water valve is opening up all the way. if not then replace valve.
OK, I would check the supply tube, to see if it may be frozen. if so, you will need to defrost it. This will occur if the inside temp is set to a non-manufacturer specifications(temp is to low). Now, if the tube is not frozen, this will lead to a failed inlet valve assembly.
The water inlet valve is located behind your refrigerator. Find the water supply line coming into the valve and turn it off at the source (typically under the sink). Disconnect the supply line. Remove the screws that secure the inlet valve in place.
The water inlet valve is connected by two wires. Label the wire placement on the water inlet valve before disconnecting the wires. The wires are connected to the terminals with slip on connectors
Firmly pull the connectors off of the terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.
Inspect the filter screen where the supply line connects. Remove any debris or deposits that may have built up using a toothbrush or warm running water. If you cannot clear the clog, it will be necessary to replace the valve (the filter is not removable on most inlet valves).
Test the water inlet valve for continuity using a multimeter. Set the multimeter to the ohms setting X100 (if available, otherwise use the nearest ohm setting). Place a probe on each terminal. The multimeter should display a reading of 200 to 500 ohms. Close inspection of the inlet valve and especially the coil may reveal the exact ohm resistance rating to test for. If the water inlet valve does not pass this test, it should be replaced.
If you have good water pressure at the washer source valves I would shut both the Hot and Cold water source supply valves off then remove the water inlet hoses at the back of the washer and inspect the water inlet screens for sediment blockage.
The washer inlet screens look like this;
If the above items check OK reconnect washer supply hoses and turn on water supply valves.If we are talking about a FAV6800AW/FAV9800AW washer then I would go into Service Mode Board Output Test page 16 of the Service Manualand turn on the Hot and Cold water valves and see if the machine water inlet solenoids operate and release water into the wash tub.I will summarize how to get into Service Mode and perform the check of the Hot/Cold washer inlet solenoids. Enter the Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00” Press the Delicates key the display will read something like “ot” the lid will lock.Now press Spin Only key this will turn on the cold water valve, do you here water flow into the washer? Press the Spin Only key to shut the cold water valve off. Now press Normal key, do you here water flow into the washer? Press the Normal key to shut the valve off or the off key to get out of Service Mode.If you don’t hear either Hot/Cold water inlet valve operate then you have a bad solenoid or loss of 120VAC applied to that solenoid valve and more troubleshooting may need to take place and possible replacement of the washer water inlet valve assembly.Post back if you have questions.
"F20" is a water inlet problem. This indicates you have insufficient water supply for the washer. Whirlpool is the manufacturer of your washer and they recommend that you unplug the washer and check the following:
1. Check water faucets to ensure they are completely turned on. 2. Check the inlet hose screens where they connect to the washer. The screens can clog with sediment over time and require cleaning. This can be a problem if you live in an area with well water and/or hard water. 3. Ensure the inlet hoses are in good shape and are not kinked.
If you check all the common sense items first and the problem still persists, you need to check the water inlet valve. To access, you will need to remove the top panel of the washer by removing the three screws that hold it in place. Once the screws are removed, the panel slides back, then off. The water inlet valve is located in the left-rear of the washer just prior to the dispenser. Double the electrical connectors to make sure they are not corroded and double check the hoses that run from the inlet valve to ensure they are not kinked. A resistance check of the water inlet solenoids (with the connectors removed) should read about 800 ohms. If the solenoid readings are abnormal, replace the valve.
