My dishwasher isn't filling with water at the beginning of the wash cycle only part way through. When it reaches the rinse cycle it fills with water like normal. The dishes look kind of clean but there is a bad residue that looks like hard water. All I can think is that the rinse agent isn't getting released either. What can I do to fix this problem myself?

Confirm 120V across the water valve terminals in a couple of minutes into a wash or rinse cycle. (when you turn it on at the beginning of the wash cycle it will drain first, and then will energize the water valve to fill up.) If there is 120V across the terminals - it may have:
faulty solenoid coil - check for continuity, replace valve if none
clogged filter or nozzle inside the valve. Try cleaning the filter, replace valve if it didn't help
Larry, The float is generally for overflow conditions and will interrupt power to the fill valve solenoid. If you are not filling completely in the time allowed by the timer, it is most likely a flow restriction in the water supply. Barring other obvious restrictions, the fill valve has filter screens on the inlet side of the fill valve, which is generally the cause of your symptoms. Be careful if you attempt to clean the screens, as the fill valves are very sensitive to debris, and can become stuck open if sediment gets past the screen. I usually replace the fill valve to avoid future problems. Hope this helps.
If you post the model number of your dishwasher plus its approximate age (in years) I can help more.
But the most common cause is a weakening pump motor. On many dishwashers, the wash pump motor is also the drain motor. Replacing that motor / pump assembly will solve the problem. While you are replacing the pump, check the heating element to confirm that it is not shorted out or broken.
For now, add a cap full of bleach to the water _after_ the initial dishwasher fill cycle ends and the wash cycle begins. White vinegar would also work, but this will not fix your problem.
I doubt that the user manual covers de-liming the Hobart Dishwasher.
If I owned this (fine, expensive) dishwasher, this is what I would do.
1.) Discard any generic, ultra-cheap detergent. Stop using gels or tablets and only use powders. Buy a box of brand name powder (like Electrosol or Cascade) You will be amazed how much difference that will make because the newest generics have mineral bulk added that build up faster then hard water does on both the stainless steel enclosure plus the silverware and even plates. White patches. I LOVE generic products and saving money, but low end dishwasher powder is one place I no longer choose a generic product.
2.) Add two cups of white vinegar to the empty dishwasher and leave it there until the morning. Run a quick cycle with no detergent added. The vinegar will be pumped out immediately after you begin this quick cycle.
3.) As soon as the dishwasher fills with water during that quick cycle and begins a wash cycle, add two cups of white vinegar and close the door and allow to run the full wash cycle.
4.) When the dishwasher finishes the drain cycle and begins to fill again, open the dishwasher and check the enclosure for remaining "lime" deposits. If they remain, keep adding 2 cups white vinegar each time the dishwasher refills and begins to wash/rinse again.
You should be delighted with the results. Long term, you should consider adding a whole house water softener and then reduce the amount of dishwasher (and laundry) detergent by one half. Amazing increase in quality of life by adding a water softener. You will be delighted.
Please post back with you results, OK? Good Luck!
What is the manufacturer and model number of the dishwasher?
Here is the process I would follow to remove the gunk.
Start a short cycle in the dishwasher, without adding detergent powder and after the (hot) water has filled the DW and the wash cycle has begun, open the DW door and add 1/4 cup of household bleach. When the water drains and begins to refill for the 2nd wash cycle, check the dishwasher to see if anything has gotten better and if not, add another 1/4 cup of bleach as soon as the hot water has refilled. Allow the DW to finish the full cycle.
Begin another short wash and as soon as the initial hot water fills and the wash cycle begins, open and add 2 cups (approximatly) of white vinegar. Allow the whole set of cycles to finish and check the insides.
If grease remains, I would use a de-greasing spray (avilable at all hardware stores and most food stores.) Spray on and use paper towels on all surfaces.
Because I do not know the make and model # for your dishwasher, I can not give you a part number for replacement racks.
When the cycle doesn't advance, it's probably the timer or a cold-water supply problem:
* It's the timer, if your washing machine fills with water and begins agitating, but the timer never advances--or if the washer is in a spin cycle and the timer won't advance. Then you need to replace the timer.
* It may be a cold-water supply problem, if the washing machine fills with water, agitates, drains, and spins, but then doesn't fill with rinse water. See There's no cold water.
My dishwasher Indesit DI67S will not run on the number 1 cycle. It will fill and then when that programme finishes it jumps straight to the drying cycle missing all the rinses out etc. If on the number 2 programme it goes all the way through but then doesn't dry. I've also noticed that the water doesn't seem to be heating up much and certainly isn't drying. Is this the element or something else? Once its reached the drying cycle the light for this just flashes then I have a job to try and reset the machine. It can take endless attempts. Will switching the machine off at the mains solve anything or is it the element? Thankyou
