What FA0 Means
FA0 comes from the DW60's frequency consistency checks. The controller measures the frequency of the incoming supply and has found it outside what it expects, which the manual attributes to incorrect input power frequency and, failing that, to the controller itself.
Common Causes of FA0
- The machine running from a generator or inverter supply
- An unstable or out-of-specification mains supply
- A controller measuring the supply incorrectly
🔧 One Safe Check You Can Try
This one points outward rather than inward. If the dishwasher is running from a generator, an inverter, or a temporary supply, that is very likely your answer, and moving it to a normal household circuit is the test.
⚠ Why You Shouldn't Go Further Than That
- Supply-side work is licensed electrical work in most places, so the circuit itself needs an electrician rather than an appliance technician.
- Replacing the controller while an irregular supply is still feeding the machine puts the new board in the same position as the old one.
- A supply problem can be damaging other appliances on the same circuit at the same time, which is worth establishing before anyone focuses on the dishwasher.
- Opening the machine to chase a problem that is coming from the wall is time and money spent on the wrong side of the plug.
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.
