Try removing the inlet pipe, and refitting, might fix it, else likely that the
Inlet water soleniod failing/failed or tiny mesh filter (it does come out for cleaning) behind the inlet hose clogged. Temporaily bypass the aquastop water stop unit; it might be the culprit!

A replacement solenoid is usually only about £10 from www.espares.co.uk, or ebay sellers (no connection with these but they are very good), fits in minutes (2 or 3 electrical spades ,and a posidrive or two) and usually fixes all water related problems. the noise you can hear is probably the solenoid trying to actuate, will be droning/buzzing sound.
could simply be stuck with some foreign matter in there that's got through the mesh filter but unlikely. they normally fail and sound terrible.

Don't throw your dishwasher away for the sake of a £10 part.
Good luck

I have the CW447 integrated dishwasher which won't fill with water


Like most electrical appliances what worked for me was turn it off at the wall for 10 mins, then turn it back on. Did you get an error code? Check the pipes are not twisted and that the water supply is turned on full. Let me know how you get on

Shortly after cycle starts, a whirring sound starts, is this a problem with the motor?


with LG dishwashers: after starting, 1st, DW pumps out any remaining water, 2nd, DW fill fresh water, 3rd, main wash motor starts, which is normally a whirring sound. (If you here grinding or rattling, then you have a problem.)

Cda cw 494 - dishwasher makes beeping noises and stops halfway through cycle . will restart if turned off but will not complete . doesnt seem to be filling properly .now and then does complete cycle and...


Greetings,
usually, open and close door..then start counting the flashes. these will give you your fault code. The code then tells us where to go from there. off hand, i would say you have a heater problem.. Either, the water is not getting hot enough because of a faulty heater, or faulty thermostat. The button above the green light that flashes try and hold that down for a minute to reset....let me know about the flashes

Matsui mf160 starts its wash cycle and timer stops


on most machines, the timer will not run if the water is not up to temp. if the inside is plenty hot mid-cycle, then your heating element is probably good. it is the thermometer that needs located and checked. if the inside is not steamy, then your heating element is the most likely culprit.
don't hate your dishwasher. it just wants to make sure that you get a full wash cycle at a hot enough temp. to get the dishes clean. good luck

Our LG LDF7920st dishwasher (6 months old)makes a whistling noise


Hey, consider the float assembly!

We bought this dishwasher and ran it for the last 1 1/2 months and it made a grinding and whistling sound from day one (it's supposed to be nearly silent in its operation). Turns out the drain pump was cutting in while the machine was still filling, thereby emptying the wash tub of any water. Then, when the cycle proceeded to wash, the dumb thing had no water and made a horrible noise. So I had to pitch in at least 2-3 litres of hot water, and then it worked quietly! Had to do this every time there was new water intake.

After working with the repairmen - four visits later, we isolated the float assembly as the problem and they set about replacing the part. Turns out the two parts were markedly different. LG HAD INSTALLED an older model float assembly at the factory and it was the problem. The replacement part was the correct float assembly and things worked perfectly after that - thank goodness. No more babysitting the dishwasher.

Don't let anyone tell you the motor assembly needs replacement. I have seen that cop-out 'fix' all over the web. But use deductive reasoning to find out where the problem is in the cycle, and explore this option first - it's a quicker and cheaper fix than replacing the whole motor assembly.

'Mr. Float' as he is now called works like this:
-expels any residual water in the tub from the last wash
-intakes water for the wash or rinse
-whirs 2-3 times prepping for the cycle
-begins to wash, quietly
-expels at the end of the wash or rinse.

He used to:
-expel residual water
-intake new water for wash or rinse
---drain pump would cut in WHILE still filling
-machine would whir once, realize it didn't have enough water
-perform a brief top-up intake shot
-begin to wash and whistle and GRIND (this is where I would have to add the water)
-expels water from wash or rinse, and start all over again.

It's a good dishwasher and it will work, but the right model parts have to be in place!

Dishwasher fills, when the pump is supposed to start it just whir


Hello, sounds like a broken wash impeller or a stripped drive impeller (the piece that fits inside the impeller). These two parts are driven by the wash motor and propell the water through the spray arms. good luck

Soap left in cups when cycle is over


If the problem is that the dishwasher isn't filling with enough water, you should replace the water valve.

If it's getting enough water, but dishes have a white film on them or are still not getting clean, you may have hard water build up in your machine. Try to run a dishwasher cleaner thru it, or depending on how much buildup you have, you may need to take the dishwasher apart and clean it. I know JetDry puts a cleaner out, but I haven't personally tried it yet.

You can usually see white buildup inside the dishwasher if this is your problem.

Cycle will not start


sounds like your machine is not taking in any water at all, which is the first thing the dishwasher wants to do on all programme settings.The constant whirring noise you refer to will be the water valve trying to take water into your machine.As yours isn't filling in the first place the programme cannot progress without water and it will just sit there whirring.Anyway, to resolve this matter I would check the fill hose which goes from the back of machine to your cold water pipe in your kitchen/utility, in case somebody has turned off supply.where the flexi hose meets the copper supply pipe there should be a thumbturn shut/open valve, turn this 90 degrees or a quarter turn and if you here a rush of water for a split second then you have fixed it.At this point try setting away a programme to see if water is going into dishwasher. If not have a bucket ready and unscrew the flexi hose altogether to make sure water is travelling past shut/open valve.If not you need a new shut/open valve.If water is able to pass this valve reconnect to dishwasher turn shut/open valve a quarter turn to open flow of water again,test machine on any programme again ,if it fills then your sorted, if not it must be your dishwashers internal water valve that will need replacing.Not a major job (located behind fill hose) but make sure electric and water supplies are off first before dabbling and write down your machines make and model number before shopping for part. GOOD LUCK.
