LOGIK L1014WM20
Hi I have a LOGIK washing machine that keeps going into E03 (to much water) it's now driving me mad .it's constantly running water through the valve. . pumps fine . I have changed the valve and the pressure switch and pressure switch pipe is clear as I can hear it bubbling when I blow down it . Nothing else really to change ? Any ideas greatly appreciated

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
LOGIK L1014WM20 overfilling with E03 despite valve and pressure switch replacement
- The problem
- The washing machine repeatedly went into E03 and continuously let water in. The drum was sometimes reported to fill to over three quarters full. The pump was said to work normally. The drain arrangement was high and the owner stated it was not siphoning.
- Likely cause
- The strongest diagnosis in the discussion was a fault in the pressure sensing system, most likely a blockage in the pressure chamber or an air leak in the pressure tubing/connections. After those were checked and cleaned, contributors said only rarer causes remained, such as wiring/connection faults between the pressure switch and PCB or a PCB fault. The exact fault was not confirmed.
- What fixed it
- The owner had already replaced the inlet valve and pressure switch. Recommended checks were to rule out siphoning, remove and inspect/clean the pressure chamber, and inspect the pressure hose for pinholes or poor sealing at each end, including trimming the ends if long enough. After cleaning the chamber and checking for leaks, the fault still remained. The owner chose not to pursue further repair and decided to replace the machine.
- Checks to try
- Confirmed pump operation
- Confirmed drain hose/waste pipe was high and not siphoning
- Observed drum sometimes over 3/4 full
- Replaced inlet/feed valve
- Replaced pressure switch
- Blew through pressure switch pipe and heard bubbling
- Removed and cleaned pressure chamber
- Checked pressure chamber for leaks
- Parts or tools mentioned
- inlet/feed valve
- pressure switch
- pressure switch pipe/tubing
- pressure chamber
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello there. I don't think I ever had to change a pressure switch, they are probably the most reliable part in the washing machine although I haven't worked on modern pressure switches, which could potentially be less reliable.
Can you actually see that too much water is going into the washing machine? Can you hear water trickling down the drain at the same time as it is filling up, or whilst it is washing, just before it starts to fill back up with water?
If you can, there is a possibility that water is siphoning out through the drain hose, causing the washing machine to constantly lose water, and therefore be unable to fill to the correct level. But there's also the chance that it is actually overfilling.
If your washing machine's drain hose is connected to the u-bend under the sink then siphoning is unlikely because the drain hose typically connects quite high up. Siphoning is caused when the end of the drain hose is lower than the level of the water inside the drum. This typically used to happen when the drain hose was pushed into a standpipe. If the standpipe fell over to one side, or the drain hose was pushed too far down into it then water would siphon out. It used to be a very common problem but as most washers connect to a u-bend it's much less likely. For a better explanation see here - Washing machine fills and drains at the same time
Regarding overfilling, if you haven't already, have a look at this article, which explains about overfilling and contains links to more articles describing in detail how the pressure system works - Washing machine is overfilling

The waste pipe.is high and it's not syphoning , the drum is sometimes getting over 3/4 full . You can hear the water constantly running which is why I changed the feed valve followed by the pressure switch . Just doesn't make sense
In that case, the only things left are a blockage in the pressure chamber, or an air leak on the pressure tubing either through a small hole, or at each end where it connects to the pressure chamber and pressure switch.
Being able to blow through the tubing and hear bubbling doesn't mean it's clear. It could have soft gooey gunge blocking it, which you can force through with your lungs, but the small amount of water that runs into can't. To be sure, you need to take off the pressure chamber and check it. If it's clear, and the pressure tubing is long enough, cut off a centimetre at each end to get a new bit of the hose connecting. That's after checking there isn't a small hole in it.

Well , I've just taken the chamber out cleaned it checked it for leaks and still the same , apart from now I have custa all up my arms 🤣 lucky Im used to working on cars
Hi bob. There's nothing else that should cause it. The system is pretty simple really, water goes into the drum and some of it runs into the pressure bottle. As water rises it forces air up the thin tubing and switches on the pressure switch.
So the only things that can cause overfilling is if air can't get up the tubing due to pressure bottle blockage, air leaking out of the tubing, or pressure switch faulty.
The latter two are very rare. Blockages more common. But if you've replaced the pressure switch, cleaned pressure bottle and checked for air leaks on tubing it shouldn't overfill.
The only things theoretically left are connection faults or broken wire between pressure switch and pcb or some weird fault on pcb, both of which are rarer still.

Well , I have tried to be Green and repair it , it's not worth me going any further as the boss is harassing me so of to Currys to pick a new one ðŸ˜
Aye you've definitely done everything you can. Not worth pursuing further.
