The ventilation outlet for drying fan has recently become quite noisy and when it has finished and the door is then open it leaves a puddle of water on the floor which it hasn't done before. It doesn't do it all the time. Can the fan be replaced.

This happens every year or two. Take off the outside front panel to access the hose that runs from the bottom of the fan down to the dispenser, and lets the water drain out through it to the interior. Clean out that hose as well as you can. Replace. This is a stupid problem that Miele should have a permanent fix for. Grrrr.

    In fact I just did this with mine today. The hose cleans out quickly, the problem is getting the front back on. 4 hands make it easier. It slips on when you start close to vertical, then slip in in and down. For putting the screws back in, you might have to use a micro screwdriver to re-align the little clips on the door panel. (You will see what I mean when you do it!)

    This costs a service call ($100, give or take) to call for service. It can be done at home with no added parts. I think it applies to all Miele dishwashers, and I have now done it several times. As I said before, this is a design fault and should not be necessary!

    Thanks Gary, this was exactly the problem with my Miele G975 Plus. That annoying sound was bugging me for months and months! I took the hose out, tried to pour water through and nothing came out; then used a skewer to push the gunk out, the water started flowing - i was surprised by how much build up was in the hose, amazing! Anyway, you just saved me a service call, well done!

The fan should be able to be replaced..It's possible that steam or water is maybe leaking through the fan or gasket around the fan area,thats all i can offer.

This is specifically for the G 646, but it is a common problem with other models. Miele should have fitted larger diameter pipes and spigots.

First clean out the pipe. Use a small piece of roughish cloth, such as from an old towel, soaked in washing up liquid, and push it right through to the other end several times with a knitting needle or similar then swoosh water through. You'll see gunky greasy sludge coming out.

When the pipe is clean, fit one end back onto the lower spigot (on the rinse aid/detergent dispenser) and blow hard through the other. You should see gunk getting blown out the dispenser (if the lids are open). Do this a couple of times until no more comes out.

Remove the pipe and fit one end onto the top spigot (on the fan housing) and blow hard again. With a bit of luck anything that gets blown out into the fan housing will get flushed through the pipe on the next cycle.

When refitting the panel (four screws on the top, three on each side), it's easiest to do the bottom of the three side screws first as the "sockets" into which they go are mounted on a moveable "bar" that needs to be aligned so the screws can be tightened. The fascia panel needs supporting/guiding from underneath while you are doing this. This is fastest done with two people but can be done reasonably easily on your own. Once the two bottom screws are in, the other 8 should locate easily. As always, if the screw doesn't start turning easily, it's probably not located properly, so take it out and try again.

My 2003 kia rio won't start I have new spark plug n wires I went through high puddle of water n it turned off won't start no more

Deep water and engines do not mix very well and if water was drawn into the air intake the engine could be a write-off. This is unlikely with just a deep puddle but it does illustrate the degree of care needed where water is concerned.

Some years ago we had to recover a car from a ford through a small river. The owner didn't realise quite how deep the water had become after a winter storm. The car dried out quite well after a couple of weeks under the workshop heater with all the doors and windows open but still would not start. The various black boxes were removed from the vehicle and the cases removed and a further week of drying out returned the car to full working order.

New plugs and wires will be no help if there is no spark. There is no point in having a spark if there is no fuel injection...

Some luck guessing what is wrong might happen but mostly guesswork is doomed to spending time and money without results and what is needed is a systematic approach to discovering what is wrong. These days that approach needs a good deal of experience, equipment and model information.

Duet front load - water fills while door is open!

This is a leaking solonoid valve.
The valves are located just inside the machine where the water supply hoses attach.
  • Remove the power plug
  • Undo the top lid of the washer
  • The valves will have some internal pipes clamped on their outlets. Remove the pipes.
  • Dry the valve outlets with tissue.
  • Turn on the water supply to the washer (if it was off)
  • Watch the open valve outlets for seepage.

There may be between 1 and 3 valves depending on the model.
You should be able to replace the leaking valve quite easily.

Fan is noisy intermittently well after wash is finished

It depends on what model you have. The fan is usually operating when the dry cycle is on. The dry cycle can be quite long compared to the actual wash (which ends when the rinse water is drained out). The dry cycle uses the steam in the dishwasher to circulate around the dishes. The fan keeps running until the full cycle is complete. If you are hearing heavy noises when the fan is running, then the bearing of the fan maybe damaged and you need to replace the fan.

Mold in door gasket, can not get rid of it...

If you can put on a pair of gloves and get a new sponge and mix 1:1 of water and clorox. Go outside in a well ventilated area with the wind behind you. Take the sponge and wet without it dripping and wipe the gasket all over. In areas you can not reach pour a little solution and swirl it all through the channel. Let it stay outside in the sun and rinse generously before installing.

Best prevention is to remove the gasket every time you finish with your wash and make sure it gets air dry. The next best thing is to leave the front door open to dry the gasket. Hopefully you don't have a status light that comes on when the door is open. Good Luck

Water keeps dripping under the fridge.

In a frost-free refrigerator/freezer the frost that would normally accumulate on the inside wall of the freezer is removed by heaters imbedded in the freezer's walls. Periodically these heaters are turn on to melt the frost which then exits the freezer as liquid water through a drain in bottom. This water accumulated in a pan underneath the refrigerator and is supposed to be removed by evaporation. If the flow of melted frost from the freezer is greater than the evaporation rate in the pan then the pan will overflow and you will get a pool of water on your floor. A bad seal on the freezer door will allow more frost to form inside. Also if you leave the freezer door open a lot you will accumulate more frost. The evaporation rate in the pan can be affected by the ventilation around it. If the vents on the bottom of your refrigerator are clogged with dust it will decrease the evaporate rate in the pan. In addition, many refrigerators have a fan the pulls air around the pan. If this fan has stopped working the evaporation rate in the pan will also decrease.

Door gasket or sealOver time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak.

Noise Problem

Is it a frost free freezer ? if it is it sounds like the evaporator fan motor making the noise

Fridge motor is very very noisy

It sounds like it could be ice around the fan motor. Unplug it and let it defrost for about 12 hrs with the doors open. Plug it back in and see if it has quit making the noise. If it did it probably needs the defrost timer replaced. Good luck. kstfas
