What product lines does Fagor Industrial cover and how do diagnostic codes vary across them?

Fagor Industrial (Onati, Spain — Basque cooperative roots) builds three technician-facing product families: commercial dishwashers (the FI undercounter / hood / rack-conveyor line, the newer UPSTER glass / dish / rack platform, and the COP / CO-COP rack-conveyor line), commercial refrigeration (CC counters, ANL / AFP upright cabinets, blast chillers — controllers from Carel or Eliwell are common OEM fits), and commercial cooking (Visual and Advance combi ovens, fryers, tilting bratt pans / kettles, ranges). Diagnostic-code conventions therefore differ by product line: dishwashers use F-codes (F1–F12 family) and AL-codes (alarms), refrigeration units inherit the underlying controller's code scheme (Carel rE1 / E0 / Hi / LO, or Eliwell E1 / E2 / EE), and the Visual / Advance combi ovens use E-codes / Er-codes plus textual touchscreen alerts. Always cross-reference the on-screen text against the model-specific service manual.

What does Fagor dishwasher error code F1 mean?

F1 on Fagor FI / UPSTER / COP commercial dishwashers indicates a wash-tank temperature probe fault — the controller is reading an out-of-range value (open, short, or impossible value) on the wash-tank NTC. Diagnostic flow: power down, locate the wash-tank probe (typically clipped to the tank wall or in a thermowell), check the resistance against the model's R-vs-T table at room temperature (most Fagor probes are 10 kΩ or 20 kΩ NTC), inspect the probe connector for moisture or corrosion, and replace the probe if the resistance is out of spec. If the probe is good, check continuity back to the controller and inspect the controller input.

What does Fagor dishwasher error code F2 mean?

F2 on Fagor commercial dishwashers indicates a boiler (rinse) temperature probe fault — same diagnostic family as F1 but on the rinse / boiler NTC instead of the wash-tank probe. The rinse boiler is the small high-temperature boiler that delivers ~85 °C sanitising rinse water; its probe failing causes the machine to lock out the rinse cycle to protect against under-temperature sanitising. Check the probe resistance, the connector, and the harness back to the controller. F-code numbering is shared across the FI / UPSTER / COP families but specific bit assignments can vary by firmware revision — always cross-check the model service manual.

How do I troubleshoot a Fagor dishwasher that won't fill?

Fagor dishwasher fill faults typically display as F4 (fill timeout — tank did not reach the fill level switch within the allowed time) or F5 (fill level sensor fault). Diagnostic order: 1) verify the inlet water supply is open and the inlet hose is not kinked; 2) check the inlet solenoid valve is opening when energised (audible click, voltage at the coil); 3) inspect the air-break / fill funnel for scale or debris blocking flow; 4) check the float / pressure-switch level sensor for fouling — commercial dishwasher level switches accumulate detergent residue and need periodic cleaning; 5) descale the inlet solenoid filter. If F5 persists with a known-good level switch, suspect controller input failure.

How do I troubleshoot a Fagor commercial refrigerator that's not cooling?

Fagor commercial refrigeration cabinets (CC counters, ANL / AFP uprights, blast chillers) are typically driven by an OEM controller from Carel or Eliwell, so the on-screen code reflects that controller's scheme rather than a Fagor-specific code. Diagnostic flow: 1) read the actual on-screen code (Carel rE1 / E0 / Hi / LO, Eliwell E1 / E2 / EE / HA / LA — these are documented on the AskWhiz Carel and Eliwell brand hubs); 2) verify the condenser is clean and the condenser fan is running — dirty condenser is the #1 commercial-refrigeration callout; 3) confirm the door gaskets seal cleanly and the cabinet is not overloaded; 4) check the evaporator for ice-up indicating a defrost or fan failure; 5) only after mechanical / airflow causes are ruled out, check refrigerant charge through the access valves (EPA Section 608 required in the US).

What error codes does the Fagor Visual / Advance combi oven display?

The Fagor Visual and Advance combi oven controllers use a mix of E-prefix / Er-prefix numeric codes and plain-language touchscreen alerts. Common families include cavity-temperature probe faults, core-probe (multi-point meat probe) faults, steam-generator / boiler faults (boiler probe out of range, boiler not reaching setpoint, water level fault, descaling overdue), door-microswitch faults, fan-motor faults (combi ovens lock out cooking if the cavity fan is not running because steam distribution depends on it), and gas-ignition lockouts on gas models. The exact code-to-fault mapping differs between Visual firmware generations and the newer Advance platform — always pull the model service manual and use the on-screen text plus the service-mode error log to confirm.

How do I clear a Fagor descaling / water-treatment alert?

Fagor combi ovens, dishwashers, and ice machines all run volume / time-based maintenance counters that prompt descaling or water-filter replacement. These alerts are informational, not active faults — ignoring them on newer firmware escalates to a hard lockout that prevents operation until the cycle is run. For combi ovens, run the guided descaling cycle from the service menu using the Fagor-approved descaler and rinse with the prescribed cycle. For dishwashers, descale the boiler and tank with the recommended chemical and reset the counter via the technician menu. For water filters, install a new cartridge of the correct hardness rating, then reset the volume counter and confirm the filter type — selecting the wrong hardness causes the next exhaustion alert to fire too early or too late.

Why does my Fagor dishwasher show "door open" when the door is closed?

Fagor dishwasher door-fault codes (typically F3 on the FI / UPSTER / COP families) cover both the physical microswitch and its harness. Diagnostic flow: 1) confirm the door is fully closed and latched (commercial dishwashers will not run with a partially-latched hood or door); 2) inspect the door microswitch for mechanical damage — these switches see thousands of cycles per day and wear out; 3) check the switch contacts with a multimeter in continuity mode; 4) inspect the harness for chafing where it routes through the door hinge — hinge-routed harnesses on commercial dishwashers are a known wear point; 5) verify the controller input is reading the switch state correctly. Replace the microswitch as the first repair if mechanical wear is visible.

Where do I find the Fagor service-mode menu and PIN?

Fagor service-mode menus are PIN-protected on combi ovens and on the newer dishwasher controllers, and the default PIN is dealer-set per site rather than published as a Fagor universal default. Service mode typically shows the error log (last N events with timestamp and code), live sensor readings, output forcing tests for solenoids and pumps, and the descaling / maintenance counter resets. For Visual and Advance combi ovens the menu is reached via a long-press on the settings icon followed by the PIN entry; for FI / UPSTER / COP dishwashers the controller has a service-button sequence on the touch panel. If the dealer PIN was not provided at install, contact the authorised Fagor dealer rather than attempting bypass procedures — service-mode PIN is part of the warranty / safety chain.

When should I call a Fagor-authorised technician versus DIY?

DIY tasks across Fagor product families: condenser cleaning on refrigeration cabinets, water-filter cartridge replacement, scale cleaning of combi-oven boilers and dishwasher rinse boilers using approved chemicals, descaling cycle execution from the user menu, door-gasket replacement, basic harness and connector inspection, retrieving the on-screen error code and the service-mode error log. Call an authorised Fagor technician for sealed refrigeration system diagnosis (EPA Section 608 recovery, brazing, TXV / EEV replacement on the refrigeration units), gas-ignition lockouts on gas combis (gas-train work requires certification), persistent F-codes after probe / harness checks on dishwashers (suspect controller or wiring intermittent), and any work on a unit still under Fagor factory warranty — unauthorised repairs can void coverage.

Quick answer

Fagor Industrial (Onati, Spain) builds three technician-facing product families with different code conventions: commercial dishwashers (FI / UPSTER / COP) use F-codes (F1 wash-tank probe, F2 rinse boiler, F3 door, F4 fill timeout) plus AL-alarms; refrigeration (CC, ANL, AFP) inherits the Carel or Eliwell controller scheme; combi ovens (Visual / Advance) use E-/Er-codes plus textual alerts.

What error codes does FAGOR display?

Tap a code for the full breakdown — meaning, symptoms, causes, and fix steps.

Dishwasher wash-tank temperature probe fault — NTC reads out-of-range. Check probe resistance against R-vs-T table, inspect connector for moisture, verify harness back to controller. Common on FI / UPSTER / COP families.

Dishwasher rinse boiler probe fault — same family as F1 but on the high-temperature rinse boiler. Lockout protects against under-temperature sanitising rinse. Check probe and harness; numbering can vary by firmware revision.

Door / hood microswitch fault — commercial dishwashers will not run with partially-latched door. Inspect switch contacts, harness chafing at the door hinge, and controller input. Microswitch wear is the most common root cause.

Fill timeout — tank did not reach fill level within the allowed time. Check water supply, inlet solenoid valve, air-break funnel for scale, level switch / float for fouling, and the inlet solenoid filter. Descale if hard-water site.

Fill level sensor fault — controller cannot read the level switch state reliably. Clean the level switch (commercial dishwasher level switches accumulate detergent residue) and verify wiring; if persistent with a known-good switch, suspect controller input.

F12

Drain / regeneration timeout family on FI / UPSTER / COP dishwashers — drain cycle did not complete in the allowed time, or water-softener regeneration cycle aborted. Check drain pump operation, drain line for blockage, and the regeneration valve assembly.

Alarm-prefix code on Fagor dishwashers — displays alongside an F-code or as a standalone alert (rinse-aid empty, detergent empty, descaling overdue, door open during cycle). AL-codes are typically informational; clear after addressing the underlying cause.

Visual / Advance combi oven error prefix — covers cavity-temperature probe, core (meat) probe, steam-generator / boiler probe, water-level fault, door microswitch, fan-motor fault, gas-ignition lockout. Exact mapping varies by firmware generation; pull the model service manual.

rE1

Carel-controller refrigeration probe fault on Fagor cabinets fitted with a Carel OEM controller — cabinet probe NTC out of range. Cross-reference the Carel brand hub for full diagnostic detail; root causes are probe failure, harness break, or moisture in the connector.

Eliwell-controller refrigeration probe fault on Fagor cabinets fitted with an Eliwell OEM controller — cabinet probe out of range. Cross-reference the Eliwell brand hub for full diagnostic detail. Eliwell E2 typically maps to the evaporator probe.
