Questions people ask
- What does E18 mean on a Bosch washing machine?
- The machine could not pump the water out in the time it expects. No. The drum is holding a full load of water and the cycle will not move on until it drains. Nothing is at risk of breaking, so there is no rush, but you will need to drain the machine by hand before you can open the door and rescue the laundry. Start here: empty the drain pump filter.
- What does E18 mean on a Bosch dishwasher?
- The water level came out too low, so the programme cannot start. The cycle will not run, but nothing is at risk and there is no leak. This is usually a supply problem, and usually free to fix. Start here: open the supply valve fully.
Do not see your machine? We publish a brand only once its codes are confirmed against manufacturer documentation and a second independent source. That is slower than guessing, and it is the whole point of the site.
This is not a coincidence of one code: we compared every code that appears on more than one brand and found that several mean the opposite depending on the badge.
