Washer-dryer combo takes an unusually long time to complete cycles.

Safety first: Unplug the unit before accessing internal parts.

• Observe cycle stages: Note whether the delay occurs during fill, wash, drain, or dry. This helps pinpoint the subsystem at fault.
• Check water supply: Ensure both hot and cold faucets are fully open and inlet screens are clean to maintain proper fill speed.
• Clean drain system: Clear the pump filter and verify the drain hose and standpipe are not restricted.
• Verify heating: During wash, feel the door glass to see if it warms on hot cycles. During dry, check for warm air. If not, troubleshoot heater and thermostats.
• Sensor issues: If the unit uses moisture or load sensors, inspect and clean sensor contacts inside the drum and check wiring. Replace faulty sensors.
