Electrical Safety Isolation
A machine that trips the breaker or earth leakage should remain disconnected until tested. Repeated resetting can expose wiring and wet components to further damage. Electrical diagnosis requires appropriate instruments and must establish whether the fault appears immediately, during filling, when the heater energises, while the motor turns or during pumping.
1. Wall Socket And Supply Test
We examine the wall socket and supply test in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
2. Mains Filter
We examine the mains filter in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
3. Heater Insulation Resistance
We examine the heater insulation resistance in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
4. Motor Leakage To Earth
We examine the motor leakage to earth in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
5. Pump Winding Fault
We examine the pump winding fault in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
6. Damaged Harness
We examine the damaged harness in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
7. Water Ingress
We examine the water ingress in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
8. Control-Board Short Circuit
We examine the control-board short circuit in relation to the reported fault and the machine’s operating sequence. The check is intended to confirm whether this area is functioning, obstructed, worn, incorrectly installed or receiving the wrong electrical or control input. Findings from this step are compared with the other symptoms before any repair recommendation is made.
