Water Overfills

Hi folks.

Recently, my Samsung washing machine was possibly overloaded by my housemate and filled up with water and displayed an error message. Foolishly, he treated it like a PC and switched it off and then on again. We think it filled with more water, and then it started leaking water from the front door.

I replaced the door seal, and the job appears to have been a success, as I just put a wash on and as the drum filled with water, there was no leakage.

However, I am now paranoid about how much water should be piped into the drum to do a wash cycle. I stood and watched the drum filling up, and it seemed to take a long time and fill with a lot of water. The drum filled with water to about half way up the window at which point I panicked, fearing another flooding of the kitchen, and switched it off.

My question is how much water (in terms of height in the window) should the machine take in for a wash (I used Rinse & Spin, the 2nd quickest cycle)? Is filling half way up the door normal, or does that sound like something is broken, like the pressure system?

Many thanks...

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Washing machine overfilling due to perished pressure hose

The problem
The Samsung washing machine was overfilling during fill cycles. Water rose to around halfway up the door window and, when left running, eventually came out of the detergent drawer. A previous door seal leak had been addressed, but the overfilling remained.
Likely cause
Loss of air pressure in the water level pressure system due to a perished section at the top of the small pressure hose. Earlier forum advice also mentioned a possible blockage in the pressure chamber or a faulty pressure switch, but the confirmed fault was the damaged hose.
What fixed it
The pressure sensor unit was accessed, the hose disconnected, and the perished end section of the hose was cut off. The hose was then reconnected, restoring correct pressure sensing and stopping the overfill.
Checks to try
  • Observed water level rising excessively during filling
  • Confirmed overfill by water coming out of the detergent drawer
  • Inspected the small rubber pressure hose at the pressure sensor unit
  • Identified the top of the hose as perished
Parts or tools mentioned
  • pressure hose

Safety: Machine was checked with the appliance disconnected from the mains.

My troubleshooting guide has a section on overfilling

UPDATE:

The machine is definitely overfilling with water. We put it on and left it this time and it filled up until water started coming out of the detergent drawer.

Can anyone help?

Ah, yes, I've looked at that, but there's nothing concrete. I've isolated it to the pressure system, but how do I actually fix it? Is it usually one aspect of the pressure system, or are there several faults it could be?

With the machine disconnected from the mains, take the small rubber tube off the pressure switch under the lid and gently blow down it. If it's got resistance there may be a partial blockage of gunge in the pressure chamber bottle at the other end which would cause levels to be too high and/or overfilling. If not, it could be a faulty pressure switch (less likely) or even a small air leak in the pressure tubing hose.

Many thanks Andy. I'll give this lot a go and see where I get.

Such a pain in the arse, because I made an exquisite job of replacing the door seal!

BTW it's hard to imagine how overloading the machine would to cause it to overfill.

I wouldn't know, I'm in uncharted terrotory. But the timing of the incidents matches up.

I still haven't got round to trying to fix it yet. I will update once I do.

When water we overfill with water to a washing machine than it does not round in proper manner. Than there are chances of damage

If overfilling started after replacing the door seal, I have to wonder if you've disturbed any wiring attached to the rear of the front panel or somewhere?

Believe it or not, I *STILL* haven't got round to addressing this issue; I've been making do with doing my washing in my friend's flat.

I hope to have a crack at it this week coming!

It didn't.

The overfill led to the seal leaking; that's why the seal was replaced. But it's still overfilling.

Well, Andy, many many thanks. I have FIXED the machine!

I worked out what the pressure sensor unit was, and unscrewed it and turned it over to disconnect the hose, as per your advice.

However, I didn't need to blow down the pipe, as the answer was staring me in the face. The top of the hose had perished, and was therefore not containing the pressure in the system.

So I unclipped it, cut the perished end section off and reconnected it and Bingo! I now have a working washing machine again.

I have a couple of pics to put up, if I can work out how to do so. It seems I can't just attach them to a post without them being online.

Anyway, a thousand thank you's, o Great One!

Edit: Managed to upload pic. Persihed hose sectioned is circled in red.

Excellent, and thanks for the update. How did it perish like that I wonder? Could it have been rubbing on something?

I suppose so. The perished bit was right where the spigot that it attaches to ends.

I suppose the years of vibration may have just worn through it, although you wouldn't have expected that.
