The control board is effectively the brain of a modern commercial washer, managing cycle timing, water levels, temperature and safety interlocks. When it develops a fault, the symptoms can be confusing — sometimes the whole machine goes dead, other times it behaves erratically, skipping steps or displaying random error codes.
Signs You Need Control Board Repair
- Machine won't power on at all
- Display shows random or unreadable error codes
- Cycles start but skip steps or stop unexpectedly
- Buttons unresponsive or triggering the wrong function
- Machine resets itself mid-cycle
- Burning smell or visible scorch marks near the board
What's Involved
We test the control board's power supply, relays and connections before concluding the board itself has failed — a burnt-out relay or a corroded connector can mimic a full board failure and is often cheaper and faster to fix. Where the board has genuinely failed, usually from a power surge, moisture intrusion or component burnout after years of service, we source and fit a matching replacement board, then run the machine through a full diagnostic cycle to confirm every function responds correctly.
Common Causes
Control boards fail from power surges (common during storms), moisture getting into the control housing, or simple component fatigue after years of continuous commercial operation.
Why Choose Washing Machines Tech
Control board diagnosis takes real electronics knowledge to get right — we test individual components rather than replacing the whole board on a guess, which keeps unnecessary costs off your repair bill.
A machine behaving erratically is often a control board issue, and it rarely fixes itself. Get it diagnosed before it fails completely mid-cycle.
