Corberó F2 on dishwasher: inability to discharge waste water
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
F2 on Corberó dishwashers (such as models CLVV7622W, CLVV7622X, CLVV6621W, and CLVV6621X) indicates that the appliance cannot discharge water because the drain hose or filters may be clogged. Cancel the program, clean the filter assembly, and check the drain hose before calling service.
Safety first
Stop and check this first
- Risk of cuts: when sponging out water and checking the wastewater pump area beneath the filters, take great care not to cut your hands on broken glass or pointed cutlery.
- Before cleaning the wastewater pump or awaiting repair, always unplug the dishwasher by pulling the plug with dry hands (never pull the cable) and turn off the water tap.
Safe checks you can perform
- Cancel the running program by holding Start/Pause for 3 seconds
- Remove and rinse the micro, coarse and metal filter assembly
- Sponge out standing water and check the pump area and drain hose
- Authorized technician inspection of the wastewater pump and wiring
Leave these tasks to a qualified professional
- Do not attempt this professional task: Clear or replace the wastewater pump using original spare parts
- Do not attempt this professional task: Correct the drain hose installation (50-110 cm height, max 4 m length)
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Clear or replace the wastewater pump using original spare parts
What they doThe authorized technician disconnects the dishwasher from the mains, shuts off the water tap, accesses the wastewater pump to remove internal blockages, or installs an original replacement pump if the motor has failed.
They must show youthe removed blockage or faulty pump and complete water discharge during the 30-second cancel cycle.
In writingfault code F2, the wastewater pump cleaning or original part replacement, and leak check confirmation.
Correct the drain hose installation (50-110 cm height, max 4 m length)
What they doThe technician inspects the drain hose behind the cabinet and at the sink spigot or wall drain, removing kinks or blockages and ensuring the drain height is between 50 cm and 110 cm with a hose length under 4 m.
They must show youthe straightened drain hose routing and unobstructed water outflow into the drain.
In writingdrain hose inspection details, verified drain connection height, and successful cycle completion without F2.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Cancel the running program by holding Start/Pause for 3 seconds
- Who:
- you.
- How:
- follow the manual's F2 remedy to cancel the program by holding the Start/Pause button for 3 seconds; the drying LED will light up while the dishwasher attempts to discharge water for about 30 seconds.
- Result that matters:
- testing whether the 30-second cancellation drain cycle clears the tub and lights the End indicator.
- If the water drains out and the End LED lights up:
- switch off the machine with On/Off and clean the filters before running another cycle.
- If water remains standing above the filter or F2 returns:
- switch off and unplug the dishwasher to inspect the filters and pump area.
- Evidence to keep:
- whether water discharged during the 30-second cancellation step or F2 reappeared immediately.

Remove and rinse the micro, coarse and metal filter assembly
- Who:
- you.
- How:
- with the dishwasher unplugged, remove the lower basket, turn the filter assembly counter-clockwise and lift it out, separate the coarse filter from the micro filter, remove the metal filter, rinse all three thoroughly under running water, and lock them back clockwise.
- Result that matters:
- clearing trapped food debris and ensuring the filter assembly is seated properly, as the machine must never run without filters.
- If the filters were clogged or loosely fitted:
- reassemble them clockwise until locked and test a short program.
- If the filters are clean but rinse water still sits above the filter plate:
- sponge out the sump and check the wastewater pump area.
- Evidence to keep:
- how much residue was on the three filter sections and confirmation that the assembly locked clockwise.

Sponge out standing water and check the pump area and drain hose
- Who:
- you.
- How:
- with the plug disconnected from the wall socket with dry hands and the baskets and filters removed, sponge out the standing water, carefully inspect the wastewater pump recess for foreign objects watching for sharp glass, and check that the rear drain hose is not twisted and connects between 50 and 110 cm high.
- Result that matters:
- removing any foreign object blocking the pump intake and confirming the drain hose is unkinked and no longer than 4 m.
- If you remove a foreign object or straighten a kinked drain hose:
- reinstall the filters and baskets and run a test cycle.
- If the pump recess and hose are clear but F2 continues:
- close the water tap and contact an authorized Corberó service agent.
- Evidence to keep:
- any foreign object removed from the sump cavity and the measured height of the drain connection.

Authorized technician inspection of the wastewater pump and wiring
- Who:
- authorized Corberó service technician.
- How:
- with the appliance unplugged from the earthed socket and the water tap closed, inspect the internal wastewater pump mechanism, electrical connections, and control output, replacing any faulty part exclusively with original Corberó spare parts.
- Result that matters:
- restoring normal water discharge safely without voiding the warranty.
- If the wastewater pump is internally jammed or electrically faulty:
- clear or replace it with an original spare part and verify drainage.
- If the pump tests good but receives no drive signal:
- diagnose the electronic board and wiring harness.
- Evidence to keep:
- replaced original part reference and confirmation of a full 30-second cancellation drain test.
Internal disassembly exposes 220-240 V wiring and sharp metal edges: authorized service personnel only with mains power unplugged.

What it means
In the instruction manuals for Corberó CLVV7622W/X and CLVV6621W/X dishwashers, automatic fault code F2 warns of an inability to discharge water from the tub. The manual states that the water discharge hose and the three-part filter assembly (micro, coarse, and metal filters) may be clogged, or that large food residues or foreign objects have blocked the wastewater pump, leaving rinse water standing above the filter. Seeing F2 on the display does not by itself prove that the drain pump is defective.

Symptoms and causes
Probable causes · in order
- Clogged micro, coarse and metal filter assembly in the sumpCommon
Food scraps and grease trapped in the coarse, micro, or metal base filters block water from reaching the sump intake and trigger the F2 fault warning.
Evidence: Corberó CLVV7622W y CLVV7622X manual de instrucciones de lavavajillas · Corberó CLVV6621W y CLVV6621X manual de instrucciones de lavavajillas
- Drain hose twisted, blocked or outside the 50-110 cm height rangeCommon
A kinked or crushed discharge hose behind the cabinet, a drain run longer than 4 m, or an outlet connection outside the 50 to 110 cm floor height range prevents draining.

- Foreign object blocking the wastewater pump below the filtersPossible
Large food remnants, fruit pits, or broken glass that bypass an improperly seated filter can jam the wastewater pump and leave rinse water above the filter.

- Internal wastewater pump failure or control board faultLess common
If the filters, pump cavity, and drain hose are completely clear yet F2 persists after cancelling the program, the drain pump or electronics require authorized service.
