Hoover Er01

Hoover error code ER01 indicates: Hoover H-OVEN 300 / 500 / 700 Steam & Pyrolytic Smart Oven: Cavity temperature sensor open circuit Er01; electronic controller reads infinite resistance from the PT500 / PT1000 oven probe..

The primary root cause for Hoover code ER01 is: On Hoover ovens utilizing H-OVEN Steam & Pyrolytic convection system, multi-point electronic heat management, and hOn digital intelligence: Broken platinum resistor probe inside cavity, heat-damaged silicone wiring behind rear insulation, or loose PCB terminal..

To resolve error code ER01: Isolate power at breaker. Disconnect sensor plug at rear. Measure probe resistance (~538 Ω for PT500 or ~1078 Ω for PT1000 at 20°C). Replace if infinite. Turn oven control to Off, isolate at main distribution board for 90 seconds, restore power and touch Timer icon for 3 seconds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hoover code ER01 persists, the physical component causing On Hoover ovens utilizing H-OVEN Steam & Pyrolytic convection system, multi-point electronic heat management, and hOn digital intelligence: Broken platinum resistor probe inside cavity, heat-damaged silicone wiring behind rear insulation, or loose PCB terminal. 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.
