Error Code F6 on Sharp QW-T13F491W-EU Dishwasher | Causes & Fix

Error F6 on Sharp : Wash circulation pump fault — pump motor not running or impeller jammed. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. ## What Error Code F6 Means on a Sharp QW-T13F491W-EU Dishwasher The F6 error code on the Sharp QW-T13F491W-EU (13 Place Setting Freestanding Dishwasher (EU)) indicates: Wash circulation pump fault — pump motor not running or impeller jammed. Sharp QW-series dishwashers monitor the water fill system, heating element, circulation pump, drain pump, NTC temperature sensor, and base-tray overflow protection continuously throughout every wash programme. When any subsystem falls outside its operational parameters the control board stops the programme and displays the corresponding fault code. ## Symptoms - F6 displayed on the control panel or through indicator lamp flashing

  • Programme stopped or paused mid-cycle
  • Audible beeping may accompany the error
  • Wash results poor if the error occurred partway through the cycle ## Common Causes - Wash pump motor winding open or shorted (typical: 50–100 Ω)
  • Pump impeller jammed with glass shards, bones, or hard debris
  • Pump motor capacitor failed
  • PCB wash pump driver circuit failed ## Tools You May Need - digital multimeter
  • Phillips screwdriver
  • flat-head screwdriver
  • soft brush (for filter cleaning)
  • isopropyl alcohol (for connector cleaning)
  • protective gloves (if glass debris is suspected) ## Step-by-Step Repair Guide | Step | Action | Result | |------|--------|--------| | 1 | Unplug the dishwasher. Remove the lower basket and both filter assemblies. | Tub base accessible. | | 2 | Reach into the sump area and attempt to rotate the wash pump impeller manually. It should turn freely. Resistance or grinding indicates debris or seized bearings. | Impeller rotation checked. | | 3 | Remove any visible debris from around the impeller. If glass shards are present, use protective gloves. | Debris removed. | | 4 | If the impeller turns freely but F6 persists, disconnect the pump motor connector. Measure winding resistance: expected 50–100 Ω. Open or shorted indicates motor failure. | Motor winding measured. | | 5 | Replace the wash pump assembly if the motor winding is out of spec or the impeller bearings are seized. | Pump replaced. | ## Safety Precautions Always disconnect the Sharp QW-T13F491W-EU dishwasher from the mains power supply before performing any internal inspection or repair. Water and electricity are a lethal combination — ensure no water is pooled in the tub base before touching any electrical components. If F1 (base tray flood) is active, disconnect power and tilt the machine to drain the base before further investigation. Wear protective gloves when removing filters or accessing the pump area in case of broken glass. ## When to Call a Technician Contact a qualified dishwasher technician if: - the main PCB or display board requires replacement
  • the wash pump motor has failed and requires replacement
  • there is a persistent internal water leak that cannot be traced to a hose or fitting
  • the door latch or hinge mechanism requires replacement ## Preventing Future Faults - clean the filter assembly (flat mesh and cylindrical filter) at least once a month
  • run a dedicated dishwasher descaler programme monthly in hard-water areas
  • use a dishwasher cleaner product every 3 months to dissolve grease from the pump and hoses
  • always use rinse aid to improve drying performance and reduce limescale on spray arms
  • inspect the door seal annually and replace if cracked, torn, or hardened ## Frequently Asked Questions ### Is it safe to keep using my Sharp with error F6?
