Rational E60 Error Code

What does Rational E60 mean?

Service 60 (displayed as E60 on some Rational SelfCookingCenter whitefficiency and iCombi models) indicates that the gas ignition box failed to initialize correctly during startup. The control system expects the ignition module to complete its self-check sequence within a defined time window; when that sequence does not complete — typically because of a speed-signal error from the burner fan circuit or a gas-settings mismatch — Service 60 is posted and the gas burner will not fire.

Symptoms

• Display shows Service 60 or E60 at startup or when a cooking program tries to fire the gas burner.
• Gas burner does not ignite; oven remains cold despite the cooking program being active.
• Fault may clear temporarily on power cycle but returns when ignition is attempted again.
• No visible flame or ignition attempt is audible from the burner compartment.

Common causes

• Incorrect gas type or gas pressure settings programmed in the service menu (most common).
• Speed-signal fault from the gas burner fan — the ignition box cannot receive an RPM confirmation from the fan circuit.
• Faulty or failed gas burner fan motor preventing the fan from reaching operating speed before ignition.
• Damaged wiring harness between the control board and the ignition box disrupting the initialization signal.
• Failed ignition box (ionization module) unable to complete its own internal self-test.

Diagnostic steps

1. Check gas type and pressure settings

   Enter the Rational service level and verify the gas type (natural gas or LPG) and gas pressure parameters match the unit's rating plate and local gas supply. An incorrect gas-type setting is the most frequent cause of Service 60 and is resolved entirely in software without any part replacement.

2. Power cycle the unit

   Switch the oven fully off at the isolator, wait 30 seconds, and restore power. A transient signal disruption can trigger Service 60; a clean power-up allows the ignition box to attempt initialization again. If the fault does not return, monitor the oven through several heat cycles.

3. Run the SD Repair program

   If Service 60 persists after a power cycle and gas settings are confirmed correct, execute the SD Repair routine from the Rational service menu. This re-initializes the ignition box firmware and clears latched faults in the module's memory before attempting a fresh ignition sequence.

4. Inspect the burner fan and wiring

   Power down and lock out the oven. Check the gas burner fan for grease accumulation on the blades or debris in the inlet that would prevent it from reaching rated speed. Spin the fan by hand to confirm the bearings are free. Inspect the wiring harness from the ignition box to the fan and to the control board for damaged insulation, loose pins, or corroded connectors.

5. Test ignition box operation

   Restore power and use the Rational service reference to command the ignition box through a manual ignition cycle in service mode, watching for the expected flame-sense signal. If the box fails to produce a spark or does not report flame sense when gas is present, the ignition box has failed and must be replaced with the correct Rational part number for the oven model.

6. Replace the burner fan or ignition box if faulty

   Replace any failed component (burner fan or ignition box) with the model-specific Rational replacement part. After replacement, re-enter the service menu to confirm gas settings, run the SD Repair program, and perform a full ignition test cycle before returning the oven to service.

When to call a professional

Service 60 on Rational gas ovens involves the gas combustion system and requires a Rational-authorized service technician if the fault persists after verifying gas settings and cycling power. Working on the ignition box, gas burner fan, or gas valve requires access to live-voltage circuits and presents a carbon monoxide and fire risk if done incorrectly. An unauthorized repair that defeats the ignition interlock or uses an incorrect replacement ignition module can cause uncontrolled combustion.
