Even new washing machines can experience error codes or quit working temporarily. Make note if the indicator "rinse" light is on and the display is flashing "E:04" on the Bosch washing machine. Check to ensure there is no water in the tub. This is a common error often associated with too many suds blocking the pump. It is caused by using the wrong laundry detergent which is not designed for high-efficiency washers. You can adjust your use of detergent and reset the machine to eliminate the error code.

Step 1

Use less detergent or the appropriate detergent for the wash load the next time you use the Bosch washing machine. Bosch recommends detergent with "HE" clearly printed on the laundry soap label. Front loaders and other high-efficiency machines don't require as much soap to wash the clothes. Laundry detergent manufacturers also make the "HE" soap to produce less suds when agitated for use in these "HE" machines.


Step 2

Clean the standing water drain pipe and the drain hose. Check for any small socks or other small items that may be blocking the hose.

Step 3

Turn the Bosch washing machine's selector to "Off." For a full reset, unplug the machine for 30 seconds and plug it back in. Turn the selector to "Drain," and restart the drain program.
