My bosch front loader washing machine is does not finish a program. Instead, an E05 error code appears.
For Bosch washing machines, the E05 error indicates no water coming into the machine, the water being siphoned out of the machine as it enters or the water comes in too slowly. Do you hear the water coming into the washing machine? If you hear the water running in and draining out, check the height of the outflow tube. If it is below the water level in the washer, lift it up to stop the water being siphoned out.
If no water is entering the washer, make sure that the water supply shut-off valves are open. Next, check for kinks in the supply hoses. Turn off the shut-off valves and disconnect the supply hoses. Check if the filters are clogged on either the washing machine inlets or at the shut-off. Some supply hoses are designed to stop a flooding problem by restricting the flow if they are damaged. Try connecting the hoses to the shut-off valves. Then place a bucket under the hose, check the water flow rate by turning on the water to each hose individually. Alternatively, just replace the hoses.
If the inlet supply is fine but no water enters the machine, then the problem is probably with the washer's inlet valve opening and closing. You can test this with a multi-meter; most washers have a trouble-shooting sheet inside the machine (near the control board) which indicates the expected voltages and resistances. The valve will need to be replaced.
If water enters the washing machine without draining out, then the problem is with the sensor that determines the water level. Some machines use a pressure switch. In that case, the air tube can be clogged. That's often simple to blow out. Alternatively, the tube could be damaged. Sometimes the switch or sensor is faulty or the wiring could be damaged. In rare cases, the control board is not getting the correct signals.
Please add a comment with the model number of the washer, if you'd like me to search for a parts list or diagram. I hope this helps.
