This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Bosch Classixx 6 stopped at spin with flashing spin lights
- The problem
- A 3-year-old Bosch Classixx 6 washing machine stopped during spin and showed three flashing spin lights. The owner believed this indicated a faulty contact board, especially as the board had previously been replaced, and was concerned about a quoted £200 replacement cost.
- Likely cause
- The discussion suggests the flashing spin lights do not by themselves confirm a failed contact board. More strongly supported possibilities mentioned were a drainage problem preventing spin, worn motor brushes, loose or burnt wiring/connectors, or a pressure switch/pressure chamber fault making the machine think water remained inside. A PCB fault was only presented as one possible cause, not confirmed.
- What fixed it
- Recommended action was to avoid replacing the contact board solely from the light pattern and first carry out basic checks. If these checks do not identify the fault, further diagnosis should be carried out by a suitably qualified appliance engineer. The exact repair was not confirmed in the discussion.
- Checks to try
- Check the exact flashing light pattern
- Check pump filter for coins, pins and lint
- Check drain hose for kinks or blockage
- Check whether the pump impeller turns freely
- Inspect motor carbon brushes for wear if the machine has a brushed motor
- Inspect wiring plugs/connectors between motor, pump, pressure system and control board
- Consider pressure switch or blocked pressure chamber issues
- Parts or tools mentioned
- Contact board / PCB
- Motor carbon brushes
- Pressure switch
Safety: Isolate the appliance from the mains before inspecting internal parts. Live electrical testing should only be carried out by a suitably qualified appliance engineer.

On Bosch Classixx/Clasixx 6 machines, flashing spin LEDs can point to a control or connection fault, but it does not always prove the main PCB (“contact board”) has failed. If it has already had one board in only 3 years, I’d want a few basics checked before spending another £200.
1. Check the exact light pattern Note exactly which spin lights are flashing and whether any wash/rinse LEDs are lit too. On Bosch machines the pattern matters, and different faults can look similar.
2. Rule out a drainage problem If it stopped at spin, a partial drain blockage is very common. Check: - pump filter for coins, pins, lint - drain hose for kinks/blockage - pump impeller turns freely If water is not fully pumped out, many machines will refuse to spin.
3. Check the motor side Worn motor brushes are common on some Bosch washers and can cause stopping before or during spin. If fitted with a brushed motor, the carbon brushes should be inspected for wear.
4. Inspect wiring and connections With the appliance isolated from the mains, check plugs/connectors between motor, pump, pressure system and control board. A loose or burnt connector can mimic a failed board.
5. Consider pressure switch / pressure chamber issues If the machine “thinks” there is still water inside, it may not spin. A blocked pressure chamber or faulty pressure switch can cause that.
6. About the PCB PCBs do fail, but they should not be condemned without checks first. Also ask whether the replacement board would be guaranteed, and whether the original fault diagnosis was confirmed.
If you’re inspecting internal parts, isolate from the mains first. For live electrical testing, or if you’re unsure, it’s best to use a qualified appliance engineer.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
