CW-XC243HU A/C Water Spray

I have water spraying out of the fan side of the unit which appears to be thrown by the fan due to water not draining from the base pan. I tilted unit back but this did not solve the problem. Please offer any advice you may have to solve this problem. Thanx!

    cleaned out. I then bleached the pan and after a period of time ran a hose with slow moving water in the unit. The drainage worked fine. However, when I put the unit back into the window case it still sprays water out of the vents on the fan side of the unit. the unit worked fine for the first two years of operation but now has this problem. It almost appears that for some reason the fan has reversed itself and instead of throwing water on the coils it throws it out the side vents. Any other suggestions?

    kstfas, by fan side I mean as you face the back of the unit, water is spraying thru the vents on the right side of the unit. I did notice that the fan blade is somewhat ahead of the shrould. I am not sure whether the blade shifted forward and is kicking out water that has accummulated in front of the shrould. My next thought is to check if the fan blade set screw loosened causing the fan blade to move forward but still spin. Do you know the proper position for the fan blade? Should it be entirely behind the shrould?

I would believe your problem maybe caused by lint or other material plugging up the fine fins of the inside of the condenser. Once you are able to see past the condenser(rear) fan blade, all the fins should be as visible as the exterior ones. The A /C unit needs to be removed from the wall/window to remove all the exterior cabinet screws or some may simply pull out of a sleeve to check for this. The shroud around the condenser & screws holding the condenser to the base need to be removed. It may then be able to swing it slightly away from the base to enable you to wire brush the lint down & away from the soft fins &/or wash it out with a water hose, do not kink the tubing. Fins can easily bend & cut. The fan blade could be re-mounted, if it was loose, at this time & it would sit somewhere half way inside the shroud. Once the condenser & shroud are remounted the fan blade should spin freely

Hi, It probably needs cleaned. Window units naturally create water in the evaporator area. The water is suppose to drain to the back of the unit through passage ways to the condensing area where the slinger ring on the condenser fan blade slings it into the condenser coil making it more efficient. There is usually a drain hole to drain excess water from the back of the unit. Any dirt or algae in the pathway of this water or the wrong tilt will cause water to build up and drip or blow out the front. Anything touching the evaporator coil allowing water to run down the obstacle into the wrong area will cause the same thing. reduced air flow will cause the evap to freeze which could also cause a water problem. Since the tilt is right and it doesn't seem to be freezing, Maybe a temporary increase in tilt and a dropper of bleach at the base of the evaporator would do it. This will kill the algae and may unblock the water flow. NOTE: It may also cause stains on a carpet or floor if the bleach water drips onto it. If you want to pull it out and clean it, most units can be pulled out of the housing and sprayed with a water hose but you need to be careful not to get water in the electrical parts of the unit. They can be covered with plastic or foil. Make sure you unplug the unit before trying to remove it. You may have to remove some screws to remove it from the housing. Hope this has helped. kstfas

    Hi,
    I'm not sure what you mean by "The fan side" I was thinking it was on the inside that you were getting water. Unless the water is flowing along the filter or something else attached to the evaporator, I don't have any other solutions for that. If you are speaking of the water being thrown through the vents on the outside, It could be that you have the unit tilted too far and it wont drain out of the drain hole which is probably kind of raised to keep some water in the condensing side of the unit. If this is the case, It shouldn't cause any problems unless it is being thrown on something that you want to keep dry. You could drill a hole in the pan to drain some excess water but you need some in there to help cool the condensor. CAUTION: Do not drill into the pan from the bottom if it has water in it. Hope this helps. Let me know.

    Hi, The fan blade position differs on different units. If it moves very much it will start hitting the shroud. I would say that in most cases the blade should be about center the shroud. This is where it would move the most air.

My Kenmore dishwasher does not drain out, What could be the problem?


No drainage, or poor drainage issues are usually caused by either a failed drain pump, or the sump area under the sprayer is clogged with debris. The sump is the area at the bottom of the tub where water collects on the initial fill. A wash pump cycles the water throughout the wash cycle, followed by the same water being drained from the unit by means of a drain pump. This area is usually covered by a coarse screen and fine screen to prevent debris from accumulating. But, over time, some debris may still get past the screens and collect in the sump. This usually results in poor cleaning results due to restricted water flow through the spray arms, and poor draining.

I would recommend you remove the lower spray arm and screens and check the sump area for obstructions. If the unit still has standing water inside, use a wet/dry shop vac to drain. Remove the drain line from your sink and pull a vacuum on the end of the dishwasher drain hose. If the water drains freely from the unit, then you probably have a bad drain pump. If the water will not drain, you have a clog somewhere. Check your drain lines and pump for obstructions.

If you have any questions, please post back with a MODEL NUMBER. I hope this helps you.

(Tilted) Plasmaire spits water into room....


What your problem is is that water coming back into your face is condesation. Appearently there is a clog preventing your condensation water from draining out the back side of the a/c You can remove the a/c from it's sleeve, take it outside and with a pump sprayer (Type used for spraying insecticide) filled with water spray around the base of the a/c where the condensor coil sits (you should see a small drain channel in this area) If this drain channel is clogged water will back up and the squirrel cage will pick it up throwing it out into the house.. Good Luck on your repairs

After cycle is complete my dishwasher doesn't fully drain water.


If there is not enough water, the dishes would not get cleaned. This could be caused by a partially closed water shut-off valve (located under the sink), or a faulty dishwasher water valve (located at the bottom of the dishwasher, behind the kick panel, on either side).

Also, There is usually two, sometimes three spray arms in a dishwasher. Make sure there is no debris blocking the holes inside each spray arm.

**Water temperature Note***

To get the best results, the water has to be at 120 degrees Fahrenheit when entering the dishwasher.

Concerning the Film(slimy looking substance).

This problem occurs due to excessive calcium build up inside the dishwasher. Try cleaning you dishwasher using a dishwasher cleaner. There are a few out there, Try Dishwasher Magic.

Dishwasher leaks from bottom left corner


If its just that corner check that it is level (if not leak could be somewhere else)

Then check your hoses and valves for holes or leaks (try putting some food dye water when running to see easier

Most likely a loose hose connector or hole in the rubber hose

Dishwasher Basics The main parts of a dishwasher are: Control mechanism
The control mechanism is located inside the door behind the control panel. Many units use a simple electro-mechanical system: a timer determines how long each part of the cycle lasts and activates the proper function at the proper time (such as the detergent dispenser, wash spray and draining functions). Units that are more expensive might have a computerized control system. Modern units also have a door latch that must be closed for the unit to run. Some also have child safety locks. Intake valve
This is where water from the home's water supply enters the dishwasher. The unit's pump doesn't pump the water into the basin – when the intake valve opens, water pressure drives the water into the unit. Pump
An electric motor powers the pump. During the pump cycle, the pump forces water up into the spray arms. During the drain cycle, the pump directs the water into the drain hose. The motor-pump assembly is mounted beneath the basin, in the center of the dishwasher. There are two main types of pump:
  • Reversible
    These pumps switch between pumping water to the spray arms and pumping water to the drain by reversing the direction of the motor. Reversible pumps are usually vertically mounted. dishwasher-11.jpg
    -->Reversible pump

  • Direct-drive
    The motor runs in one direction, so the direction of flow is switched from spray arms to drain by a solenoid that opens and closes the appropriate valves or switches one hose connection to another. Non-reversible pumps are usually horizontally mounted. dishwasher-12.jpg
    -->Direct-drive pump

Dishwashers can be installed in either a portable or a permanent configuration. Portable units have finished sides and top that can be used as a countertop. When not in use, the machine sits in place next to the wall. When it's time to run a cycle, the unit can be rolled on casters over to the sink, where it connects to the faucet and plugs into a nearby outlet. In a permanent installation, the dishwasher goes underneath the existing countertop and bolts into place. Hoses underneath the kitchen sink connect directly to the hot water line and the drain line, and the unit usually plugs in under the sink as well. Both types of installation require a 120-volt grounded line.

No pressure on certain settings


Dear Osville,
It is not clear what type of lance or nozzel you have. You said that the machine works fine with the circulating water jet(the turbo). So it seems the machine is fine. I do sometimes service variable nozzels and variable lances. But the best solution is to replace nozzels and variable nozzles and lances with new ones. Regarding the fan spray setting it could have no pressure because it might be in the chemical setting. The chemical setting lets out a fan shape flow of water, but with less pressure. The chemical system only works on low pressure in domestic washers, that is why it needs a low pressure flat spray. The pencil jet has 2 jets comming out because if it is a lance or nozzel with ball bearings, these ball bearings must have stuck in a wrong position. Also 2 jets can come out, due to a damaged nozzel hole.
Altogether, the best advice is to buy a new nozzel or lance...which ever your machine uses. All Karcher machines have their own specific nozzels, lances and high pressure hoses. You cannot change these from one model to another.
Regards,
Fulltech.

Dishwasher doesn't spray


It sounds like your dishwasher is doing everything normal EXCEPT washing. The unit fills properly, the timer advances properly, the unit drains and goes through a rinse cycle, plus the water is heating. I would check your main wash pump for obstructions that may be clogging it, or if it is not running at all, you need to check the interconnecting wiring and/or something in the wash pump circuit that would prevent it from running. There should be a wiring diagram/tech sheet located behind the lower kick panel under the door. I hope this helps some. Good luck and let me know what you find.
