Water Level Pressure Switch

Washing machines fill with water during the wash cycle. To prevent overflowing, or too much water from entering the tub of the machine during the wash cycle, a water level switch is installed. The water level switch is connected to the console with a tube running down into the machine. When the water reaches a certain level in the tube, the machine stops filling. If you are having troubles with the water level in your machine, adjust the water level switch. Remove the screws from the control panel. Slide a putty knife underneath the control panel on each side to depress the holding clips. Push the control panel back. Pull the wires off the water level switch to expose the connectors. Set a multimeter, a device used to test electrical current, to the X1 setting. Touch one probe to the first connector and the other probe to one of the two others. Test in pairs. You should always receive a reading of infinity or zero. Otherwise, remove the switch and replace. Follow the tube down the outer tub. Shorten the tube with a pair of scissors to adjust the final water height of the tub. Cleveland Van Cecil is a freelancer writer specializing in technology.

How To Adjust Washing Machine Water Levels

Washing Machine Pressure Switches. This video will show you the associated faults with a washing machine pressure switch and air chamber. To order your washing machine pressure switch you will need your full model number This is normally around the washing machine door frame on a sticker. The Washing machine will not go into spin; it turns as though it wants to but then stops. The most common cause for this is the pressure chamber being blocked, or the pressure switch not resetting, either way the machine thinks it still has water in it and will not go into spin. An easy way to check is to remove the hose connected to the pressure switch blow into it and listen for clicks depending on what level settings it has will depend on how many clicks there are, this will happen the instant the hose is removed so be aware, if you hear a click it means the switch has reset so the chamber is possibly blocked but if there is no sound then either you missed it or the switch is at fault. To test the switch you may have to remove it because you will need to blow into it and listen for one or more clicks as the different levels set. Be aware that some of the older machines have multi level switches, whilst the newer ones only have a single level. The pressure switch controls the fill valves, and in some cases will prevent the motor from going into spin. It operates via an internal diaphragm which triggers one or more switches depending on the type of pressure switch. Water entering the drum as the machine fills gradually fill the pressure chamber and traps the air already in it. As the water level in the drum rises so the pressure on the air increases, this air is then forced up a small bore tube which connects both chamber and switch. When the correct pressure on the internal diaphragm is attained the corresponding switch is activated. It could be the pressure chamber is blocked, if so you will probably notice more water in the machine and the cloths coming out wetter than usual. The problem here is the pressure switch is not operating, this can have a number of causes, either the switch is faulty, there is a hole in the pressure pipe or it has come off, or the most common reason is the pressure chamber is blocked. If it was screwed on then it will go back in the same position but if it was held on by a clip or glued in place then make a note of the hoses location because if it was put back wrongly positioned you could have more water in the drum than needed resulting in a flood. A related problem with similar symptoms is simply that the hose s to the pressure switch are clogged up. Check the switch itself as above, but clean out the hoses i. Or at least check them by blowing through. I am glad I could help you with this problem. The belt is fine the water has been emptied below. Want to be able to fix this myself. I forced air from the pressure switch side of the hose down and felt some resistance. I need to go the other way! Thanks for the answer. This is helping. Could that cause an F20 error? Hi Paul — I have an elderly 90 neighbour with advanced dementia — who has an AEG lavamat washing machine — with an error code C6 on it. The machine was only replaced yesterday by a very good builder having been moved out for a week, while flooring was replaced, due to a burst pipe!

Answer Bennett, there would not be a way to adjust the pressure sensor as it is pre-programmed into the control. Newer units are designed for high efficiency and will only fill the water so high to allow the pulsator to operate properly. Answer BLHWWC, With this issue, it will most likely be caused by a control board that is sending power to the cold water valve rather than to the hot water side.

Hi all My dishwasher indesit DIFP36 is not filling with enough water which is causing a number of issues: you can clearly listen the re circulation pump pulling air then water then air then water I've tried opening the machine's door while it's washing and manually throwing in about 1L of water and when it resumes it starts working properly so I'm quite sure the issue is not filling with enough water. After much Googling I found some posts that suggest how to adjust the pressure switch but the one on my machine seems to be different. My question is really which screw adjusts the filling level. I've looked inside the machine and I could not find any easier way to adjust this. There is an air tube that goes from the bottom of the machine ie the recipient just under the metal grid inside the machine directly to this switch and that's it. I've blown into the switch and you hear the clicking sound when pressure increases so it should be ok. Can someone please point me to where I can find information about adjusting the pressure switch or, otherwise, if there is any simpler way to make the machine load more water? Thanks Pedro. That model is not known in the uk. But you can't adjust the Presure switch otherwise it will leak out of the door and cause more probs. I've made several claims under Warranty but surprisingly Indesit has changed a number of expensive parts but they don't seem to have a clue about what's going on. I've even made a claim directly to the manufacturer but they refused to exchange the machine and are unable to fix this. It's a very clear case of insufficient water as adding it manually during the wash solves the issue. The other side of the issue is that it doesn't rinse properly since there's not enough water and it circulates badly creating serious health concerns about the detergent left on the dishes. Hi all I just wanted to share a quick update on my progress: I manually adjusted the Air Pressure Switch this is an Indesit DEA air pressure switch model C and I now have the machine working in top shape! To increase the amount of water you should turn the center screw clock wise. This screw will be sealed by some sort of red glue. Just turn it with some force and this glue will release the screw. In my machine the Air Pressure Switch is activated aproximatelly at mid fill. This has increased the qty of water and the machine is working very well. You can run a quick program a pre wash to check if it's filling up correctly and repeat the adjust-test process until you're satisfied. The machine should be leveled at all times when you are testing. I recommend you run a couple of Complete long cycles to check everythting is ok. Then secure the position of Air Pressure Switch adjustment Screw with a bit of super glue only put a small amount on one of the sides, so that you can later re adjust if necessary. This will keep in place even with the machine's vibrations. My machine has been working great so far and I hope it keeps up it's the great results. As rocks1 said you can make the machine overfil if you misadjust them. Therefore make these adjustments carefully. Take small steps at a time. If the machine starts mis behaving for example filling and then immediatelly expelling the water you've probably turned the screw too much and it's trigering the overfill protection mechanism; go back and undo what you did last. Disclaimer: Air pressure switches are really sensitive devices. Always mark your starting position and make small icnrements. I can't and won't be responsible for any damage that may occur while attenpting this. Most of all, I wanted to share my experience that may be useful to others.

How to Adjust a Washing Machine Water Level Switch

T he water level switch aka pressure switch senses the water level in the wash tub. It does this through a plastic tube which runs from the switch in the control console down to the side of the outer tub, near the bottom. The tube is filled with air. As water enters the tub it also enters the tube. As water climbs inside the tube, it pushes on the air trapped inside and increases the air pressure. When the air pressure reaches a certain level, it triggers the switch. Caution : Please read our safety information before attempting any testing or repairs. Before testing the water level switch, unplug the washer or shut off the power at the fuse box or breaker panel to avoid an electrical shock hazard. A defective pressure switch can interfere with the cycles that depend upon the switch to indicate when water has filled or emptied from the tub. It can also result in underfilling or overfilling of the tub. The switch routes current from the timer control to the temperature switch and the water inlet valve when the tub needs to be filled. Once full, the pressure switch cuts the current and reroutes it to the motor on the timer control to continue the cycle. Inspect the air tube for kinks, breaks or damage. The tube should also be free of water. The tubing should be securely connected to the bottom of the outer tub and to the bottom of the water level switch. The water level switch has three connectors. Label and disconnect the wires from the switch. Test the switch for continuity using a multitester. Set the multitester to the ohms setting X1. It will be necessary to test each of the three possible pairs. Place a probe on two terminals and note the reading. Now move one of the probes to the other terminal and note the reading. Finally test the third pair and note the reading. The multitester should display a reading of infinity or continuity for each test. In this test two of the pairs should read infinity and one should read near zero resistance continuity. Now blow gently into the air pressure connection and retest. It should click and you must maintain the air pressure while testing. For the two pairs that read infinity one should now show good continuity. The pair that previously gave of reading of continuity should now give a reading of infinity. Click here to order replacement parts. Gallery Reviews Search.
