KitchenAid Dishwasher Not Filling With Water? It May Be The Water Supply Line!
A KitchenAid dishwasher not filling with water can halt your kitchen workflow and leave you with a stack of dirty dishes. In most cases it comes down to issues with the water supply line such as leaks or clogs that prevent flow. In that case you’ll hear the Kitchenaid attempting to fill, but it ends up never occurring.
In addition to that, the float switch and water inlet valves can also be the cause. I’ll break all of these possibilities down next and hopefully you’ll be able to pinpoint which of these may be causing your issue.
Lets dig in!
Inspecting the Water Supply Line
First things first, ensure your water supply line isn’t tangled or kinked—such knots can restrict the flow of water into your dishwasher.
Hot water is crucial, so check that the water supply is fully open.
A simple test is to run the faucet nearest your dishwasher to confirm there’s adequate water pressure.
Checking the Water Inlet Valve
The water inlet valve is the gateway for water to enter your dishwasher and is operated by a solenoid.
Over time, debris can clog the valve, or it may be defective.
You’ll need to locate the valve, usually found behind the lower kickplate.
With a multimeter, test for continuity; no continuity indicates a need for replacement.
Examining the Float and Float Switch
The float mechanism prevents overfilling by rising with the water level, triggering the float switch to shut off water intake.
Check for a stuck float—it should move freely up and down.
If there’s no issue with the float, test the float switch with a multimeter for continuity. A lack of continuity means it’s time for a new switch.
The Door Latch Mechanism
Your KitchenAid dishwasher’s door latch is crucial for safety and proper operation, ensuring the door stays closed during a cycle.
Testing the Door Switch
To check if your door switch is working, you’ll need a multimeter. Here’s a step-by-step process:
- Safety First: Disconnect the power supply to avoid shock. You’ll be dealing with electrical components.
- Locate the Switch: It’s usually behind the dishwasher door panel.
- Set the Multimeter: Adjust it to the continuity setting to test if a current can pass through the door switch.
- Test the Switch: With the door closed, attach the multimeter leads to the switch terminals.
A functioning switch will show a reading (or an audible beep); no reading indicates a malfunctioning door switch.
Assessing the Latch Assembly
The latch assembly holds the door closed and signals the dishwasher that it’s safe to run a cycle.
- Examine the Latch: Inspect it for obvious signs of damage. The latch should securely catch the door.
- Check Alignment: Make sure the latch properly aligns with the catch.
- Look for Wear: Over time, the latch can wear out due to constant use.
- Replacement: If the latch assembly is broken, it’s time for a new one.
| Signs of a Faulty Latch Assembly | Action to Take |
|---|---|
| Misaligned door | Adjust latch |
| Door doesn’t stay closed | Replace latch |
| Dishwasher won’t start cycle | Check power & switch |
| Audible clicking but door won’t latch | Inspect latch and catch mechanism |
