Samsung ecobubble not always filling
Hi. Quick question.
My washing machine doesn't always fill correctly and start the cycle.
Pressing start, the washing machine will some times start to fill, stop and start and stop filling.
It sounds like a water hammer starting and stopping. Like water running, clunk stop, pause and repeat.
If I turn it off and on then press start. It will empty the water in the machine and try to start again. Sometime it will then work perfectly or repeat the problem.
If I turn the tap on while it's filling I can see the pressure change while it's attempting to fill and then stop and fill again.
Cheers.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Samsung Ecobubble intermittently starts filling then stops repeatedly
- The problem
- The washing machine would sometimes begin a cycle normally, but often the fill would start and stop repeatedly with a water-hammer type noise. Power-cycling would make it drain and retry; sometimes it would then run normally, sometimes the fault repeated.
- Likely cause
- Most strongly supported diagnosis was an intermittent poor electrical connection at the water inlet valve, or a fault within the valve/solenoid itself. A faulty relay on the PCB was also suggested as a possibility, but not confirmed.
- What fixed it
- Recommended action was to resistance-test the water valve and gently move the valve connector while testing to see whether it goes open circuit, indicating a bad connection or internal valve fault. It was also suggested to check that there was no air trapped in the fill hose. No confirmed final repair was posted.
- Checks to try
- Pressure sensor checked: reported as 0 when empty and about 20 kHz when full
- Solenoids reported as receiving 240V and appearing to operate
- Pump-out reported as working correctly
- Visual observation that water pressure at the tap changed as the machine attempted to fill and stop repeatedly
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Water valves have a very high resistance. Could it be a poor connection on the water valve or inside the valve? Try taking a resistance reading and gently move the connector on the valve up and down to see if the reading goes open circuit.
Also check there isn’t air in the fill hose pipe somehow.

I've checked the pressure sensor. It's reading 0 when empty and 20 odd khz when full.
Solenoids seem to be reading a sensible voltage.
Pump out seems to be working okay.
Washer will sometimes work fine. But will often do this problem from the video.
That sounds weird. Sorry I’ve not heard it before and struggling to think what it could be. It doesn’t sound like a pump or a water valve or the motor.

It sounds like a drum turning for half a second with water inside but the drum isn't moving. The only way to see where this noise is coming from is to take off the top on the back panel and carefully locate where the noise is coming from with the ears. Please let us know if you find out what the problem is or more information

Thanks for the reply.
The drum isnt moving. The sounds is a water hammer effect caused my the solenoids turning on and off.
They are getting 240v not problem and are working.
The water pressure switch is working correctly.
The sound at the start of the video is the water being emptied and gargling.
Tje second half of the video is the water hammer noise of the machine staring to fill, being stopped and trying to fill again.
There is a test menu for these Samsung machines. But I can't find it for my model.
Cheers.
Do you know if I can get a service manual? There seems to be Samsung service manuals for other models online. Bit not mine. I messaged Samsung but they wouldn't give me one.
No the white goods manufacturers do not supply any service manuals at all unless you are in the trade and pay, at least not in the UK.

I've never heard water hammer like that. Water hammer it is when the pipes loudly knock against the floorboards or woodwork. However, if the valves are definitely turning on and off and there is a proper water supply to the valves it sounds like a very poor connection or maybe even a faulty solenoid or relay in the PCB somewhere.
