Display shows HO; cycle time is extended; dishwasher appears to pause while waiting.

Safety note: This is often an informational code indicating extended heating time.

• Run hot water at sink: Before starting the dishwasher, run the hot water tap until water is hot. This reduces the time needed to heat water inside the dishwasher.
• Check water heater setting: Ensure your home water heater is set to at least 120°F (49°C).
• Test heating system: If HO appears frequently and dishes are not hot, test the heating element and temperature sensor as described for i60.
• Inspect for scale: Hard water scale on the element can reduce heating efficiency; descale if necessary.
