"HO" flashes on display during washing.

When the dishwasher is in the wash cycle "HO" flashes on the display.  When it is is the rinse cycle the display goes back to the time left in the entire cycle.  I looked in my manual and can't find anything related to this. Is this normal or could there be a problem with the water flow?

The HO actually means the system is in a water heat delay. It means the water wasn't hot enough and the dishwasher is heating it up. Mine does it during the Hi-Temp wash.

When you have the HO indication it usually means that the water temperature coming into the dishwasher is not hot enough. A good practice to prevent this is to turn the water on at the kitchen sink until the water is hot. Then start your dishwasher.

The display is flashing HO, what does this mean?


I was wondering the same thing. This is what I found:

The display shows "HO" or "Hd." What does this mean?
HO" or "Hd" means the dishwasher's cycle time is being extended while it is heating water. At certain points in the wash cycle, the dishwasher uses hotter water to ensure a clean load of dishes. If it detects that the water is not hot enough, it will heat it.

If you're seeing "HO" or "Hd" frequently, check the temperature of the water available to your dishwasher. It's best to do this at the sink closest to it, allowing the hot water to run until it reaches its maximum temperature before you test it with a thermometer. For best results, water should be not less than 120°F.

Can you tell me what temperature the dishwashers reach during each part of cycle--Dishwasher model is WDF902SA Food authority have asked this of me


Hello,
The wash temperature for a high temperature commercial dishwasher should be around 140F AND 160F. The final rinse temperature should be 180F to meet health code regulations. The final rinse temperature is reached during the end of the cycle for a few seconds. If the machine is a low temperature dishwasher the wash temperature and rinse temp will be around 140 F to 160 F. The sanitizing of your warewash will be done by the use of chlorine or iodine in the low temp application.

Check to see if you have any switches on your dishwasher that could by pass a rinse cycle. Use a hotter temparture when washing, Check your water level,check your filters on your inlet hose top and bottom. When it gets to a rinse cycle you should hear it drain out and bring in fresh water. you could change to a liquid detergent. Dont over load your dishwasher. make sure you are using rinse aid and try adjusting it up one setting. Shiney glasses means your rinse add is working. NZL
