Bosch Dishwasher F2 Error Code: Causes & Fix

What is the Bosch Dishwasher F2 error?#

F2 on a Bosch or Gaggenau dishwasher is a wash-motor fault — the circulation motor that drives the spray arms has failed or stalled, so the water simply sits still and nothing sprays. That motionless-water symptom is the giveaway that separates F2 from a heating or sensor code: the cycle timer may advance, but the dishes come out completely unwashed. It is rated a professional-only repair, and there is a safety edge to it: if your breaker trips when F2 appears, the motor winding has a ground fault. In that case do not keep resetting the breaker — cut the power and call a technician, because a short to the chassis can energize the machine body.

F2 on a Bosch Dishwasher: likely causes and repair cost#

On a Bosch Dishwasher, the F2 code signals: motor problem.

Typical professional repair: $400–$700 · Difficulty: professional only · usually a technician job

Symptoms that often accompany F2: No wash action — the water just sits still; Humming with no spray-arm rotation; Circuit breaker trips partway through the wash; Dishes come out completely unwashed; The cycle timer advances but nothing sprays

Technician diagnostic sequence for F2:

1. Disconnect power and access wash motor from below the tub
2. Check motor winding resistance (expect 3-10 ohms across terminals)
3. Spin motor shaft by hand — should rotate without catching or grinding
4. If motor tests good, check board motor driver circuit for burned MOSFET

Parts a technician may check or replace: wash motor assembly, Gaggenau; control board, Gaggenau

Field note: F2 is the Gaggenau wash-motor fault (the same BSH motor platform as Bosch 800/Benchmark), but the giveaway that separates it from a heat or sensor code is mechanical: water sits perfectly still because the impeller never turns. The motor is interchangeable with Bosch, yet the mounting bracket differs — order the Gaggenau-specific kit, which includes the correct bracket. Spin the shaft by hand first: a free-spinning shaft that still will not run points to the board driver, while a notchy or seized shaft is the motor itself.

Safety note: If the circuit breaker trips with F2, the motor winding has a ground fault. Do not reset the breaker repeatedly — this indicates a short to chassis that could energize the unit body.

How to troubleshoot the F2 error yourself#

F2 is a professional-only repair, so honest DIY is about safe triage rather than a fix. First, the safety check: if the circuit breaker trips whenever F2 shows, stop — that points to a winding short to ground, and repeatedly resetting the breaker risks energizing the cabinet. Leave it off and call a technician. If the breaker holds, you can do one useful thing before the visit: with the power disconnected, try to turn the wash-motor shaft or spray-arm hub by hand. A shaft that is notchy, gritty, or seized means the motor itself is failing, while a shaft that spins freely yet still will not run under power usually points to the board's motor driver. That information saves diagnostic time. What you cannot safely do is access the motor from below the tub, test its windings, or swap it — on Gaggenau the motor is a specific kit with its own mounting bracket. Once F2 is confirmed, this is a technician job from here.

Is the Bosch Dishwasher F2 error worth fixing?#

F2 is the repair where I tell owners to weigh age honestly, because it is the priciest common fault on these machines. A professional wash-motor repair runs $400 to $700, reflecting a costly part and involved labor. On a high-end Bosch Benchmark or a Gaggenau that cost a great deal new and is still under about eight years old, that is worth it — a comparable replacement costs far more, and the rest of the machine has years left. Where the math turns is an older unit near the top of the range: once F2 approaches $700 on a dishwasher past a decade, you are spending a large share of a new machine's price on one repair, and replacement becomes reasonable. Spin the shaft first — if the fix is only the board driver rather than the whole motor, it lands lower and the decision gets easier.

Bosch Dishwasher F2: frequently asked questions#

What does the F2 error mean on a Bosch Dishwasher?#

F2 means the wash motor that circulates water to the spray arms has failed or stalled, so no water moves and dishes are left unwashed. On Gaggenau it is the same BSH motor platform used across Bosch.

Is it safe to keep using a Bosch Dishwasher that shows the F2 error?#

Not really — if the breaker trips with F2, the motor has a ground fault and repeatedly resetting it risks energizing the cabinet. Cut the power and leave it until a technician has checked it; otherwise the machine simply will not wash.

Can I clear the F2 error myself, or do I need a technician?#

You can safely spin the motor shaft by hand with the power off to help pinpoint the cause, but the repair itself is professional-only: accessing and replacing the wash motor is a technician job.

How much does it cost to repair the F2 error on a Bosch Dishwasher?#

A professional F2 repair typically runs $400 to $700, covering the wash-motor assembly or, in the cheaper case, the board's motor driver. It is the most expensive common fault on these dishwashers.

Which parts usually fail when a dishwasher throws the F2 code?#

The wash motor itself is the usual failure, whether from worn bearings or a winding fault. A free-spinning shaft that still will not run points instead to a burned driver on the control board.

Why does wash motor failure trigger the F2 error?#

When the motor winding shorts, seizes, or the board's driver burns out, the impeller cannot turn and the spray arms get no water. The board detects that the motor is not running and raises F2, leaving the load unwashed.
