Asko Dishwasher: water inlet fault

Professional Repair Guide

What is this symptom?

Experiencing a water inlet fault with your Asko dishwasher? This issue, often indicated by error codes F12 or F67, means your dishwasher isn't filling properly with water. The problem could stem from a closed water supply valve, a faulty inlet valve, or an issue with the control board or float switch. Understanding the cause is key to restoring your dishwasher's functionality.

Urgency: Medium

Important Tips for Asko Models

  • Error codes such as F12 or F67 correspond to water inlet faults; ensure supply is open and inlet filters are clean as initial steps.
  • Official documentation indicates water pressure requirements (e.g., 4.2-140 psi) for proper filling; low pressure may trigger inlet fault codes.

Possible Causes

Water supply valve is closed or insufficient water supply

How to Identify: Dishwasher does not fill at all; check under sink if the valve is fully open and water flows to the machine.

Part: Water supply shut‑off valve and water line

Faulty water inlet valve (electrical or mechanical failure)

How to Identify: Dishwasher fails to fill/dishwasher stops mid‑cycle; humming or buzzing sounds without water flow; error codes related to inlet fault; testing shows no continuity.

Part: Water inlet valve

Control board not supplying power to inlet valve

How to Identify: Inlet valve does not actuate even with good water supply; testing inlet valve shows proper function but no action when commanded.

Part: Control board

Faulty float switch or water level sensor

How to Identify: Dishwasher misreads water level, cycle stops unexpectedly, or error codes related to water level.

Part: Float switch/water level sensor
