Teka disposal stops shortly after starting, or will not start, and an E04 code appears on the electronic control module (where fitted).

Safety first: Isolate power at the breaker. Do not repeatedly restart a stalling motor as it can overheat and damage wiring.

• Step 1 – Check for jams: Follow the jam clearing procedure from E03 to ensure the grinding plate spins freely by hand with the service key.
• Step 2 – Verify free rotation: With power OFF, rotate the shaft several full turns. Any grinding, tight spots, or scraping noises indicate bearing or plate damage.
• Step 3 – Inspect for water ingress: Look for signs of water leaking onto the motor housing or terminal box, which can cause short circuits and overcurrent.
• Step 4 – Reset and test: Press the reset button, restore power, run water, and test briefly. If E04 reappears within seconds, discontinue use.
• Step 5 – Professional diagnosis: Overcurrent faults after clearing jams usually mean a failing motor. A technician can test winding resistance and insulation; in most cases the complete disposal unit is replaced.
