Washer-dryer displays incorrect time remaining or behaves unpredictably with cycle times.

Safety first: Unplug before accessing sensors or control boards.

• Observe patterns: Note whether time jumps occur during heating, rinsing, or spinning. This can indicate which sensor is misreading.
• Run maintenance wash: Clean the machine internally to ensure sensors are not affected by residue.
• Check NTC and pressure switch connections: Reseat connectors on the temperature sensor and pressure switch.
• Factory reset: Some Bush models allow a user reset (refer to manual). If behaviour remains erratic, the main PCB may require professional diagnosis or replacement.
