Motor Drive (Triac) Short Circuit

What it means

This code appears on electronic Indesit washing machines and means the main board has detected a short circuit in the part that switches the motor (the triac) or in the motor wiring. The machine stops at once to protect itself, and the same number can mean something else on other brands. Codes differ between some Indesit series, so check your manual to confirm.

Models covered: Indesit washing machines on the electronic EVO platform; the code shows on the display or as blinking lights. Older mechanical models do not show codes.

• A faint burning smell may come from the machine.

Possible causes5

• Failed motor triac on the main board.
• Moisture or a water leak reaching the motor or its wiring.
• Shorted motor wires from chafing or rodent damage.
• Failed motor windings.
• Carbon brushes worn so far that they spark against metal parts.

How to diagnose5

1. Unplug the machine, wait a few minutes and restart once only; if the code returns, do not keep retrying.
2. Check for water pooled under the machine or a visible leak from the hoses.
3. The technician unplugs the machine before opening it, then inspects the motor wiring and connector for burning or moisture.
4. The technician measures the motor windings and brushes and compares them with the manufacturer specification.
5. If the motor is sound, the technician checks the main board for burn marks around the motor circuit.

How to fix5

1. Dry the area and fix any water leak before running the machine again.
2. Repair or replace damaged motor wiring and connectors.
3. Replace worn carbon brushes.
4. Replace the motor if the windings are faulty.
5. Repair or replace the main board at an authorized service center, then run a test cycle to confirm the code is gone.
