Control Board (PCB) Failure: Diagnosis and Repair

Random error codes and a machine that won't behave consistently often trace back to the board controlling everything.

What This Fault Looks Like

Erratic behaviour, random error codes, the machine getting stuck mid-cycle, or no response at all.

If this sounds familiar, you’re not alone — it’s one of the more common washing machine faults our technicians repair across Pretoria homes.

Why This Happens

In most cases, power surges, moisture damage, or simple component ageing on the circuit board are the typical causes.

How We Repair It

When you book a technician for this fault, we run diagnostic tests on the board, repair minor faults like damaged relays or connectors where possible, and replace the board entirely if the damage is extensive.

We carry common replacement parts for most major brands, including Defy, Samsung, LG, Bosch, Whirlpool, and Hisense, so many repairs are completed in a single visit.

Should You Try to Fix This Yourself?

A quick word of caution: Some of these issues — like clearing a simple blockage — are safe for a confident homeowner to check first. Others involve electrical components or moving parts that carry real risk if handled incorrectly, and a misdiagnosis can end up costing more than the original repair would have. If you’re ever unsure, it’s worth getting a professional opinion before attempting a DIY fix.

A Final Note

Load shedding-related power surges are an increasingly common cause of control board faults in Pretoria.
