Error Code E6 on Toshiba DWS-22AHK Dishwasher | Causes & Fix

Error E6 on Toshiba : Wash pump circulation fault — wash motor failed or impeller blocked. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. ## What Error Code E6 Means on a Toshiba DWS-22AHK E6 indicates the wash circulation pump motor has failed to start, stalled during operation, or the PCB pump driver circuit has detected a fault. The wash pump circulates water through the spray arms at high pressure during wash and rinse cycles. On DW-14F series dishwashers the wash pump draws water from the sump and forces it through the upper and lower spray arm supply channels at 0.8 to 1.5 bar to dislodge food soils from dishes. A stalled pump motor is audible as a humming sound at the start of the main wash phase without the sound of water circulating. If the pump hums but does not circulate water, the impeller is blocked. If there is no sound at all from the pump, the motor winding has likely failed open-circuit. ## Symptoms - E6 displayed on the digital panel

  • Wash cycle paused or halted
  • No water entering, no draining, or no heating as expected ## Common Causes - Wash pump motor winding failed (OL)
  • Wash pump impeller blocked by a broken glass fragment, bone, or label
  • Capacitor (on single-phase AC pump models) failed
  • Air trapped in the pump housing after installation
  • PCB wash pump driver circuit damaged ## Tools You May Need - digital multimeter
  • Phillips screwdriver
  • narrow-nose pliers
  • magnet-tipped retrieval tool ## Step-by-Step Repair Guide | Step | Action | Result | |------|--------|--------| | 1 | Unplug the dishwasher and remove the lower basket, spray arm, and sump filter to access the pump impeller chamber. | Pump access obtained. | | 2 | Inspect the impeller for debris — broken glass, labels, or bones are common blockages. Remove any obstruction. | Impeller checked and cleared. | | 3 | Disconnect the wash pump motor connector and measure winding resistance — expected 5–30 Ω. OL confirms a failed pump motor. | Motor resistance measured. | | 4 | If the pump reads OL, replace the wash pump assembly. Ensure the replacement pump impeller rotates freely before fitting. | Pump replaced. | | 5 | Restore power and run a Normal wash cycle. Listen for strong water pressure from the spray arms to confirm pump operation. Verify E6 does not recur. | E6 cleared. | ## Safety Precautions Unplug the dishwasher before reaching into the sump or testing the pump motor. Check carefully for broken glass before inserting hands into the sump area. ## When to Call a Technician Contact a Toshiba authorised service technician if: the fault persists after replacing the identified component; if PCB-level or refrigerant-circuit work is required; or if you are not comfortable working with electrical components. ## Frequently Asked Questions ### Is it safe to keep using my Toshiba with error E6? If error E6 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the dishwasher with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error E6 on a Toshiba ? Repair costs for error E6 on the Toshiba dishwasher depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Toshiba-authorized service provider for an accurate estimate based on your specific situation. ### What does error code E6 mean on a Toshiba dishwasher?
