E32 — Moisture Sensor / Heating Circuit Fault

E32 is not in Bosch's official US dryer error-code list (which only documents E01/E02 as a pair, E06, and an E08/E09/E24/E25/E28/E90 electronics group). The 'moisture sensor / heating circuit fault' explanation below is not confirmed on Bosch's US consumer page — verify against your model's manual.

How to fix it

  1. Open the door and remove the lint filter from the door opening.
  2. Pull apart any two-piece filter assembly and remove all lint by hand.
  3. Rinse both filters under warm running water until clean.
  4. Allow the filters to air-dry completely before reinstalling — wet filters can cause humidity errors.
  5. Reinstall the filter assembly firmly until it clicks/seats.
  6. Press the acknowledge button (varies by model — often Start or a dedicated reset) to clear the reminder.
  7. Begin a new cycle to verify the code is cleared.
