Understanding Washing Machine Error Codes
Modern washing machines use electronic fault codes to identify problems. When something goes wrong, the machine stops and displays a code on its display panel (or flashes its indicator lights in a specific sequence on machines without a display). These codes can save you significant time and money by pointing an engineer directly to the faulty component.

What to Do With an Error Code
Note the code down and try the simple checks suggested above. If the simple checks do not resolve it, share the code with your engineer when booking — it can significantly reduce diagnostic time and therefore cost. An engineer who knows exactly what they are dealing with before arriving can often bring the right part with them and complete the repair on the first visit.
