Candy Eh

Candy error code EH indicates: Candy Brava / RapidÓ / DiVino Smart Touch Dishwasher: Heating circuit safety thermal overheat Eh; water temperature sensor detects temperature exceeding 85°C..

The primary root cause for Candy code EH is: On Candy dishwashers utilizing Brava high-pressure wash hydraulics, Maxi Tub basket architecture, and Smart Touch / hOn Wi-Fi telemetry: Welded heating relay contacts on main PCB keeping heater powered continually, or defective NTC sensor..

To resolve error code EH: Disconnect mains immediately. Measure heater relay output voltage with machine in standby (must be 0V AC; if 230V AC present, relay is welded). Press and hold Start/Reset for 5 seconds until the LED rapid flash ends, close door to initiate 60s drain cycle, then power off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Candy code EH persists, the physical component causing On Candy dishwashers utilizing Brava high-pressure wash hydraulics, Maxi Tub basket architecture, and Smart Touch / hOn Wi-Fi telemetry: Welded heating relay contacts on main PCB keeping heater powered continually, or defective NTC sensor. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
