If you're looking for help fixing your Cafe Dishwasher, look no further! Our comprehensive Cafe Dishwasher Troubleshooting guide will explain common issues, provide tips, and show you how to read your model's error codes.

DISHWASHER DOES NOT DRAIN 
If your dishwasher is not draining, you may see water at the bottom of the tub. If excessive water is standing in the bottom of dishwasher, there are a few things that can cause this issue. 
Check for a blockage: 
On models with a Fine and Ultra Fine filter, remove and check the Ultra Fine filter and Fine filter underneath. For more information, visit: Dishwasher - How to Clean Fine and Ultra Filters. 
On models without an Ultra Fine filter at the bottom of the tub, 1-2 cups of clean water covering the bottom of the tub is normal. 
On models with an Ultra Fine Filter, water in the sump (filter area) is normal, but should not cover the bottom of the dishwasher. 
Make sure there is not paper or large objects covering or blocking the sump area in the rear of the tub. Clear out large pieces of food from the bottom of the dishwasher, like noodles, lettuce, bones, etc. 
Check the drain hose where it connects below the sink for blockage or a kink in the hose. New dishwashers come with a white corrugated drain hose, which should be used. Re-using old, worn out drain hoses may promote kinking and blockage. 
Make sure the kitchen sink drain is not clogged. If a disposer is installed, run the disposer to clear the drain system. Do not put hands into the garbage disposer, as serious injury could result. You should always turn on your garbage disposer prior to running the dishwasher to clean out any food or debris within the drain system. 
If an air gap is installed, remove the cap and remove any debris. Clearing the air gap will allow water to flow better as the dishwasher drains.  
If a disposer was recently installed or replaced, make sure the drain plug inside the disposer was removed.  
Do not use drain cleaner in the dishwasher. 

DISHWASHERS - BLINKING LIGHTS OR BEEPING SOUNDS 
Dishwashers equipped with an electronic control may start displaying blinking lights or have beeping sounds. This alerts the user that the dishwasher may need attention. 
Beeping Sound, Blinking, and Will Not Start: 
A beeping sound every 30 seconds: Indicates the dishwasher door was unlatched during the cycle. Close the dishwasher door to resume the cycle. 
Blinking "Start/Reset" light: Indicates that the dishwasher has been reset and is in the process of turning off. This light will blink for 75 to 90 seconds, depending on the model. View a short video about blinking lights: 
Other blinking lights or beeping sounds: May indicate a problem with the dishwasher caused by power surges. Try pressing the "Start/Reset" pad to reset the dishwasher and wait 2 minutes. If the problem persists, reset (reboot) the dishwasher by turning off power to the unit at the house circuit breaker/fuse box for 30 seconds. Restore power and the dishwasher should function normally. 

DISHWASHERS - WILL NOT RUN, HAS LIGHTS OR SOUND 
If your dishwasher will not start, but has power (light or sound), then there are a few things you can do to get the dishwasher to run again. 
Check the Control Lock Feature 
Control Lock Feature: Electronic models have a child lock-out feature to prevent the dishwasher from accidentally being turned on.  
Door Not Latching Properly 
Make sure there is nothing preventing the door from closing securely, like trim, insulation, the countertop, etc. 
Make Sure the Delay Start is Not On 
On models with a delay hours button, the delayed start feature may be activated.  
Sleep Mode 
Some models have a Sleep/Sabbath Mode, which turns off all lights and sounds to turn this feature on/off. 
Demo Mode 
Make sure the dishwasher is not in Demo Mode. For more information, view: Dishwasher - Demo Mode. 
Dishwasher Making a Slight Humming Noise But Will Not Run 
Models starting with GDF/GDT/PDT/CDT/DDT/ADT/ZDT: Add one pint of hot tap water to the bottom of the dishwasher and allow it to run for five minutes. 
For other models, view: Hums and Will Not Fill. 
Check if the Flood Float is Stuck 
GDF/GDT/PDT/CDT/DDT/ADT/ZDT models, view: Dishwasher Flood Float. 
Leak Detection Feature 
For models with an LCD display you may have a leak protection feature that is preventing your dishwasher from running.  

DISHWASHER POOR WASH PERFORMANCE 
If there is food or detergent residue left on your dishes, there are a few things you can do to resolve this issue. 
INSTALLATION 
Make sure the dishwasher is connected to the hot water line and not to cold. 
Is the dishwasher level from side to side and front to back? Improper leveling can lead to a number of cleaning issues, including affecting how well it can drain the dirty water from the tub. 
A drain hose installed over 72"H will not drain well and can affect wash performance. 
INCOMING WATER 
Check the water temperature. Proper water temperature is essential to achieve optimum results from your dishwasher and the detergent. Hot water is needed to dissolve and activate the detergent so that it can loosen and remove common food soils. The hot water heater should be set to deliver at least 120 degrees Fahrenheit water to the dishwasher. 
To check the water temperature, run the hot water at the kitchen sink and measure the temperature of the running water with a candy or meat thermometer. Adjust the temperature of the water heater accordingly. 
To be sure that the dishwasher is filling with the hottest possible water, run the hot water faucet at the kitchen sink prior to operating the dishwasher. 
Avoid running the dishwasher during or immediately after hot water is being used for other activities, like filling a bathtub, etc. 
Check the water pressure. The water pressure to the dishwasher should be 20 - 120 PSI (3/8" O.D. copper water line or 1/2" O.D. plastic water line). 
CYCLE SELECTION 
Check the wash cycle selection. Select the appropriate cycle for the dish load. Selecting a short or light wash cycle may save water and energy, but may not provide proper wash action for a heavily soiled load. If food remains on the dishware after the cycle, a longer cycle may be required. 
Use the added heat options to increase water temperature inside of the dishwasher. For example, use "Hot Start", "Added Heat", "Wash Heat Boost" or similar options if your dishwasher is equipped with these features. 
On models with Single Rack wash or Wash Zones (Upper & Lower wash), make sure this feature is not selected.  
DETERGENT / RINSE AID 
For optimal wash performance, we recommend using a high rated detergent, such as Finish Quantum Powerball , and a rinse agent. 
Do not use liquid dish detergents that are not made for automatic dishwashers.  
Check the amount of detergent and the water hardness.  
FOOD DEBRIS 
Excessive amounts of food may clog the dishwasher filters and reduce wash performance. If any jets (holes) within the wash arms are blocked, use a small object such as a paper clip or tweezers to loosen and remove the debris. Be careful not to damage the jets in any way as that will affect wash performance. 
On models with a removable ultra-fine and fine filter, take out the filters and clean them. These filters should be cleaned once a month to ensure optimum wash performance. Dishwasher - How to Clean Fine and Ultra Filters 
To prevent food debris from entering the dishwasher, scrape dishes before placing them in the dishwasher.
