Bosch 800-series and Benchmark dishwashers are common in Collin County remodels - and so are E15, E24, and E25 on the display. In Dallas-Fort Worth hard water, those codes rarely mean a random electronics mystery. They usually point to a float switch stuck from mineral film, a drain path blocked by the fine microfilter homeowners skip, or a circulation issue after scale packs the sump. This guide explains each code in plain language, what you can safely check, and when to book same-day dishwasher repair.
E15: water in the base (leak / float)
E15 means the float switch in the base pan detected water. Sometimes it is a real leak from the door gasket or a weeping circulation pump. Just as often in DFW, hard-water splash and condensation pool in the base after a high-temp sanitize cycle, or the float sticks from mineral film. Do not keep running cycles - water in the base can short the control. Wipe visible water if you can safely pull the kick plate, then book a visit so we can dry the base, test the float, and find the source.
E24 and E25: drain faults
E24 / E25 point at drain performance. Pull the coarse filter and the fine microfilter under it - Bosch owners often clean the top screen for years and never touch the microfilter. Check the air gap and the disposal knockout / tee. If those are clear and the code returns, the drain pump impeller is jammed or the pump has failed. Typical drain-pump repair across DFW lands in the mid hundreds with parts and labor; you get a flat quote before work.
Hard-water habits that prevent the next code
- Use rinse aid every cycle in Plano, Frisco, Allen, McKinney, and Rockwall ZIP codes.
- Clean both Bosch filter layers monthly - coarse and fine.
- Run a manufacturer-approved cleaner every 1-2 months to cut calcium on the heater.
- Keep the disposal knockout open and the air gap clear so drain codes are not false alarms.
Frequently asked questions
What does Bosch E15 mean?
E15 means the base float detected water. It can be a leak, condensation, or a stuck float from mineral film. Stop cycles and have the base inspected - do not keep running the machine.
How do I clear Bosch E24 or E25?
Clean both filter layers, check the air gap and disposal drain path, then run a drain/cancel cycle. If the code returns, the drain pump likely needs professional service.
