Specifications

PresenterPresentation NotesThe following is a specification chart for this years lineup. Take a few moments to review.

Things to Note about our models! Cleaning

For a dishwasher to clean properly the internal temperature must reach

120 degrees

Rinse Aid Rinse aid improves Drying and

Rinsing performance. The Rinse Aid Lamp will light if rinse aid is low, if this happens

30 mins will be added to the cycle

Sanitize If Sanitize is selected the water

temperature will reach 162 degrees. Delicate can not be selected if sanitize

option is used

NTC Thermistor NTC stands for negative temperature

Coefficient. As temperature cools, resistance rises. All dishwashers use

this type of thermistor

Turbidity Sensor The turbidity sensor is used to check water

clarity

ECS Sensor The ECS is used on the 2013 DW80F

model, to measure water temperature and presences of water

The numbers in parentheses in the Last Rinse column represent the temperature when you select Sanitize. When you select the Auto or Normal cycle, you can eliminate the (flexible) steps depending on the soil level of the dishes. The water consumption and wash time time varies depending on the steps or options you add, and on the pressure and temperature of the supplied water.

Water Too Soft (oversudsing) can leave deposits on clean dishes. Too Hard can cause spotting/staining and poor wash ability

Dishes -- Too Dirty (garbage disposal), Too Clean (oversudsing) Thoughts? (Drain Suds Lock) Detergent -- Chlorine, Enzyme, All-in-one & Tablets (oversudsing) Thoughts? (Suds Lock) Rinse Additive -- Liquid in dispenser, All-in-one Thoughts?

Which Detergent Ingredients Give Best Dishwasher Performance ? Detergent with a separate rinse additive in the dispenser gives better drying performance. For tough baked on soils an Enzyme detergent is better at hydration of the food soils. For staining such as tomato, coffee and tea, a detergent with Chlorine bleach will work on the stains much better than an Enzyme based detergent. Now that phosphate content in dishwasher detergent has plummeted to 0.5 percent from as high as 8.7 percent, conditioned (soft) water is even more critical. The reduction of phosphates may cause spots and film on dishes that can form when the minerals and food bits combine during the wash. It is important to test water hardness for wash ability complaints.

- The driving part stops. - The main PBA or Inverter PBA is out of order. - The communications connection for the main PBA or Inverter PBA is not properly connected.

LE - When the water leakage sensor data is equal to or less than 3V for 3 seconds.

- If sensor data over 3V is detected after draining (20 seconds on/5 seconds off) is performed for 3 minutes, the drain pump is turned off. If data over 3V is detected, draining is performed for 3 minutes and then the sensed data is checked again.

- There is a water leak.

OE - When the overflow sensor data is equal to or less than 3V for 5 seconds.

- If sensor data over 3V is detected after draining (20 seconds on/5 seconds off) is performed for 3 minutes, the drain pump is turned off. If data over 3V is detected, draining is performed for 3 minutes and then the sensed data is checked again.

1E Case1) HPS detected water level Condition 1) When the high pressure switch (HPS) does not measure a high level after the completion of the water supply. Condition 2) 2-1) If the high pressure switch measures a low level for 3 continuous seconds while a wash is performed, the HPS is checked again. If a high level is detected, a normal operation is performed. If this is repeated 5 times, an 1E error occurs. 22) If the high pressure switch measures a low level for 3 continuous seconds while a wash is performed, the HPS is checked again. If a low level is detected, additional water is supplied for a predetermined period of time. If a low level is measured even after additional water is supplied twice, an 1E error occurs. Case2) power consumption of Circulation pump detected low water level


- The motor is out of order. - The HPS is out of order. - If there are Bubbles in the tub - If the filter micro is clogged

Trouble Shooting Code When occur Symptom Possible Causes 3E Condition 1) When Main receives the Circulation pump error from the inverter, stop the drive the motor and restart again. If Main receive the motor error 11 times, turn off the motor for 5 minutes. At the third rest time, Error occurs. (When an error occurs, Heater is stopped immediately. And Heater ON after operating the circulating motor 10 seconds.) Condition 2) Washing(Rinsing) area : When Target rpm is 2600rpm or more and Circulation pump speed is 2400rpm or less continuously for three seconds, the operation is stopped. Retry 2 times in 3 seconds. When sensing 3 times, Inverter is turned off and retry in 5 minutes. At the third rest time, Error occurs. (If the condition of Low level water sensing, this error is ignored.)

DO NOT REPLACE THIS PART

If a unit gets an LE error code that means the unit has a leak somewhere. The safety switch is doing its job dont replace it. Water is activating the leak sensor.

These switches hardly ever fail but too many are being

replaced

Technical Info Leak Detector

PresenterPresentation NotesDO NOT REPLACE The leakage detector. If a unit gets an LE error that means the safety switch is working correctly and you have a leak somewhere that is leaking down and activating this switch. These switches hardly ever fail but too many are being replaced.

2013 Model Review & Updates

PresenterPresentation NotesThe following section will review the 2013 dishwasher, DW80F800 and 600. This section will cover the latest service bulletins and product review.

79

DW80F OE error codes

Solution: Make sure the dishwasher and case brake are level. If they are, replace the main PCB. The main PCB software was updated to open the vent and run the drying fan to decrease pressure that may build up inside of the tub. The table below shows when the changes in production took place. Units produced after the production date listed below already have the updated software.

Issue: If the incoming water supply is too hot, air pressure inside of the tub will increase causing the water level inside of the overfill sensor to increase and make contact with the probes.

82

If the water that is supplied during the initial water fill is too hot, it will cause an increase of air pressure in the tub. The increased pressure will cause water to be forced out of the bottom front corners of the tub during the first few rotations of the spray arms. After the first few rotations of the spray arm, the pressure will equalize and the water will stop dripping from the corners.

DW80F Fix for water leakage from the corner of the door

PresenterPresentation NotesThe Problem: If the water that is supplied during the initial water fill is too hot, it will cause an increase of air pressure in the tub. The increased pressure will cause water to be forced out of the bottom front corners of the tub during the first few rotations of the spray arms. After the first few rotations of the spray arm, the pressure will equalize and the water will stop dripping from the corners.

83

1 Make sure that the dishwasher is completely level from front to back. If the unit is leaning too far forward, it will increase the likelihood of water dripping from the door corners. 2 Replace the Main PCB with the parts listed in the table below. The software has been updated to version 32. The new software will open the door vent and operate the drying fan during the water supply. This will allow the dishwasher to vent any excess air pressure that may occur. 3 Change the left and right cushion duct with the parts listed on Service Bulletin ASC20131231001

DW80F Fix for water leakage from the corner of the door

PresenterPresentation NotesTo correct this situation, please preform the following steps:

Number 1 Make sure that the dishwasher is completely level from front to back. If the unit is leaning too far forward, it will increase the likelihood of water dripping from the door corners.

Number 2 Replace the Main PCB with the parts listed in the table below. The software has been updated to version 32. The new software will open the door vent and operate the drying fan during the water supply. This will allow the dishwasher to vent any excess air pressure that may occur.
