Bosch WFL2067GB will rinse and spin but not wash
I have an elderly WFL2067GB that is happy to rinse, spin, freshen up etc but refuses to wash. Starting a cycle results in a brief burst from the inlet valve followed by several minutes of nothing. After that, the Rinse LED flashes which, according to the manual means water isn't getting in. It will rinse etc so I know the water supply and inlet valve are fine.
I had a thought that possibly it was trying to heat up a small amount of water as a self-test but replacing the heater did not help. Could it be the thermostat in the same unit?
All suggestions welcome. I've replaced the machine with a spare Aquarius from the garage (never throw anything away, although that one needed a motor) so time is not of the essence. I've swapped so many carbon brushes on the Bosch I've become quite attached to it and would like to keep it running.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Bosch WFL2067GB rinses and spins but will not start wash cycle
- The problem
- An elderly Bosch WFL2067GB would run rinse, spin and freshen-up programmes, but on a wash cycle it gave a brief inlet-valve burst, then sat idle for several minutes before the Rinse LED flashed to indicate no water entering. The owner had already replaced the heater, with no change.
- Likely cause
- Most strongly supported diagnosis is a fault with one section of the water inlet valve assembly, likely the detergent-fill valve/solenoid. The discussion notes that even cold-fill machines can use multiple inlet solenoids, so one failed solenoid can leave some functions working while wash fill fails.
- What fixed it
- Recommended action was to check the inlet valve assembly and test the individual solenoids for continuity, comparing readings as they should be similar. The exact repair was not confirmed in the thread.
- Checks to try
- Observed brief burst from inlet valve at wash start
- Rinse LED flashed with manual indication of no water entering
- Confirmed machine would still rinse, spin and freshen up
- Heater was replaced but did not cure the fault
- Advised to test individual inlet-valve solenoids with a continuity meter
- Parts or tools mentioned
- heater
- water inlet valve assembly
- individual inlet-valve solenoids
- continuity meter
Safety: Isolate the appliance from the electricity and water supply before dismantling or testing components. Further diagnosis should be carried out by a suitably qualified appliance engineer.

It sounds like a water valve isn't letting water in? Is it a hot and cold fill machine? Normally a washing machine will fill with water using one valve for several seconds to flush water into the sump hose. Then it will switch to another valve to flush detergent into the machine. If this valve is faulty or has some other issue (including no water supply) then many washing machines will stick.

Thanks Andy. It's a cold-only machine so I guess the obvious candidate is the detergent valve. I'll check that out.
Yes even cold fill only washing machines often have more than one solenoid in. Some can have double or even triple solenoid valves and one can fail leaving others working ok. You should be able to test the individual solenoids with a continuity test meter. They should all have the same reading. They have a very high resistance.

Thanks again. I'll do some dismantling over the weekend.
