Fisher & Paykel AquaSmart Washer Fault 113 (AC Pump Thermistor Short Circuit)

Fault 113 reports the AC pump thermistor as failing or damaged, specifically as a short circuit. That thermistor watches the pump drive for overheating, and F&P again directs the repair to the motor control module because the sensing lives there.

What 113 Means

Fault 113 reports the AC pump thermistor as failing or damaged, specifically as a short circuit. That thermistor watches the pump drive for overheating, and F&P again directs the repair to the motor control module because the sensing lives there.

Common Causes of 113

  • A shorted thermistor on the pump drive circuit
  • Heat stress from a pump running against a restriction
  • Moisture reaching the pump sensing circuit

🔧 One Safe Check You Can Try

Before booking, check the drain path - hose kinks, a blocked pump filter, a standpipe that is too tight. A pump working against a restriction is what makes pump thermal protection matter in the first place.

⚠ Why You Shouldn't Go Further Than That

  • Unplug the machine before the pump or module area is opened, since the pump runs from the mains side of the module.
  • Clearing the drain path is worth doing, but it will not clear a shorted sensing circuit on its own.
  • Tipping the machine to reach the pump spills whatever the tub is still holding onto the floor.
  • Pump housings seal on gaskets that do not reseat reliably once disturbed, which is how a repaired washer starts weeping underneath.

Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.

FAQ

113 FAQ

Not necessarily. The code is about the sensor watching the pump drive, not about the pump itself, though a pump that has been working hard is worth checking at the same time.

Because a pump struggling against a blockage heats its drive electronics quickly, and the thermistor is what lets the module back off before something is damaged.
