Bosch Washer Error Codes
Bosch washers show E codes, often with an F code meaning the same thing, such as E18 and F18. Current 24-inch compact models can also show newer codes like E:00 with a number. Many drain codes clear once the drain hose, siphon and pump are clean, and Bosch documents each step.
Choose your code below for its meaning and the steps to try.
- E18 Drain fault: the washer can't drain because the hose, siphon or pump is blocked.
- E17 Water supply time exceeded: the washer didn't fill in time, usually from clogged inlet filters or low pressure.
