F8E0Steam valve failureCheck the water supply hoses for kinks. Check for a restricted screen in the water valves. Replace the steam valve if defective.
Steam valve
F8E1No water detectedMake sure that both water supply valves behind the washer are fully open. In winter, check the fill lines for freezing. Check the drain system for a siphon problem. If the water valve assembly is defective, replace it.

F8E2Dispenser failureThe dispenser can't move into position. Unplug the washer and check the mechanical linkage on the dispenser housing. Repair or replace any damaged dispenser parts.
Dispenser assembly parts
F8E3Overflow conditionUnplug the washer and, if the washer is overfilled, check the water valve assembly for proper shut-off of water flow. If the water valve assembly is defective, replace it. If the washer is empty when this error code appears, replace the water level pressure switch.

F8E4Low water flowThe flow meter detects a long fill time. Make sure that both water supply valves behind the washer are fully open. In winter, check the fill lines for freezing. Check the drain system for a siphon problem. If the water valve assembly is defective, replace it. If water flows normally, replace the flow meter.

F9E1Long drainRemove excess suds; the washer can't drain excessively sudsy water. Check your house drain system for a clog. Check the drain hose for kinks or clogs. Replace the drain pump if defective. If the washer drains properly, replace the water level pressure switch because it isn't accurately detecting the water level.

Remove all drain plugs, open any valve you can and have. split apart any union, and depending on the part of the country you live in, the permafrost is a factor. If you freeze below ground, then you will also need to empty your pool down below the lowest inlet fitting and then blow the water out of the lines.
Once clear of excess water, plug the holes so rain water does not refill them!

• heater will have 2-4 drain/winter plugs
  
  • also remove the pressure switch
• pump will normally have 2 plugs
  • Open & remove lid from hair & lint pot
• Pool sweep booster pump has 1 plug

Any low spots in the plumbing will trap water in them. Drill & tap a hole - 1/4" Normal pipe thread - that is the most common size of a winterizing drain plug. Others may just cut the pipe right at the lowest spot and glue in a union for future winterizing.

There are videos all over YouTube that cover this subject quite nicely.

Is it SUE or SUD code?
Sud SUDS LOCK (Overdose of detergent detected during the wash cycle) The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If "Sud" is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Potential Causes

• If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
• Check the drain hose and make sure it is not plugged or kinked
• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
• Check / Clean Drain Pump Filter of foreign objects
• Check Drain Pump
• Check the Pressure Switch
• Check CCU

Question:

How do I close my pool for the season?

by Osko Pool n Spa Information
By following the provided instructions, you will be able to professionally close your pool for the winter season. Additionally, you will protect it from winters abuse and make opening it next season...simple.

Required Tools
a) Standard Screw Driver
b) Phillips Screw Driver
c) Ratchet Set
e) Plumber Pliers
f) Sump Pump
g) Extension Cord
h) Garden Hose
i) Five Gallon Bucket
j) Air Pump or Shop Vac
k) Pool Vac & Accessories

Required Chemicals
a) Pool Shock
b) Algecide
c) Chlorinating Tablets

Required Accessories
a) Winter Cover
b) Pool Pillows or Inner-tubes
c) Chlorine Float Dispenser
d) Water Bags (for ingrounds only)

Step One - Debris & Chemicals
Remove any debris from pool water by use of a leaf rake attachment.
Add the appropriate amount of shock treatment to the pool water, as prescribed on the packaging.
Add the appropriate amount of algecide to the pool water, as prescribed on the packaging.
Run your filter for the appropriate time to circulate all water once.
(see your filter documentation for your size pool)
Install your floating Dispenser and winterizing tablets.

Step Two - Vacuum & Water Level
Vacuum your pool while setting your filter to the "back wash" or "waste" setting.
(this will help lower your water level)
After vacuuming, install the sump pump and drain pool to about 6 inches below your thru-the-wall skimmer.

Step Three - Parts Dissassembly & Cleaning
Disconnect all ladders, filter systems, hoses, solar reels and/or other accessories.
Using standard household cleansers, thoroughly clean all ladders, solar reels and/or other accessories.
Dissassemble filtration system.
Remove sand, cartridge or DE powder from your filtration tank.
Thoroughly clean all filter system parts.
Allow all items to dry.
Store all items in an area that will not be subject to freezing temperatures.

Step Four - Pillow & Cover Installation
Inflate all pool pillows or inner-tubes.
Install one pillow for every 15' of linear water surface.
(example: a 15' x 30' would require at least two pillows)
Tie pillows to pool area via nylon rope and place equally with respects to pool walls and each other.
(this is extremely important! This prevents freeze damage)
Install winter cover as prescribed by the covers manufacturer.

Step Five - Winter Tips
During the winter months, remove any excess snow from the winter cover.
(If you have a solid cover, this will prevent excessive weight form tearing you cover)
(If you have a mesh cover, this will prevent excessive water build up)

Hey, Your Finished! Congratulations, you just saved money while doing a professional job

They recommend using plumbers antifreeze or RV's antifreeze, flush it down the toilet and let it sit in the drain pipe so the pipe won't freeze. Also is a good idea to insulate the piping, this will also prevent it from freezing.

You are doing the right thing here. Its kinda goes against what your try to do if you evaporate the water that you just took out of the air to cool it?? So you have done the right thing. just keep your filter clean and you will be in good shape. also service the unit before you shut it down for winter and then again just before you start it up for summer and it will give you good service for a long time.. hope this helps .. let me know...

FL= Flood Condition
FL flashes if any overfill condition occurs. This condition occurs when excessive water in the tub causes the overfill switch to trip. The control must realize that the trip was due to an overfill condition instead of a suds lock condition in order for FL to be displayed.

With an overfill condition, the beeper repeats a warning every 10 seconds with no time out. The pump is cycled in drain mode for 30 seconds on 30 seconds off until the overfill switch resets or power is discontinued to the unit.

Note: Press STOP/CANCEL to clear display on all error codes

Causes of flood condition. Inlet valves stuck on, sediment in water level pressure tube, water pressure tubing vibrated off the switch. Bad switch (highly unlikely).

Other codes:
PF power failure
Er control lost settings during PF
LF Long fill Clogged inlet screens
CE Com error between motor and control
Ld Long drain Clogged/slow drain/pump
CA/CI Motor amping up
ob off balance load
Sr relay failure no control to motor
LS Lid switch no signal from lid switch, error occurs if the motor and control disagree as to the position of the lid switch. Usually means corosion is buit up in the switch and the motor knows the lid is shut but the control does not. Code appears when start button is pressed.
open lid= flashing display time If the lid is opened time remaining flashes in display. Close lid and press start to continue.
SL Suds Lock Current draw on motor is sensed by motor control and a suds lock is declared. The control trys 3 times to fix this by doing a mini cycle, SL is displayed if the unit was unable to correct the problem. This problem is caused by:
Bad pump
Extra heavy load
Excessive detergent
or Excessive suds/wrong stuff
