You load the dishes, close the door, and press start. The dishwasher hums or clicks, but you don't hear water running. You open the door a bit later, and the tub is still dry.

A dishwasher not getting water is a common problem, and it's frustrating. Your dishes sit dirty, and you don't know where to start. The good news is that the cause is often simple. A closed water valve, a door that didn't latch, or a stuck float switch can all stop your dishwasher from filling. Other causes, like a failed water inlet valve, need a repair.

This guide walks you through what to check, starting with the easiest fixes. You'll also learn which parts commonly fail, when it's safe to DIY, and when to call a technician. If you'd rather skip the troubleshooting, our team offers fast dishwasher repair with same-day service.

Not sure it's only a water problem? Our guide to common dishwasher problems and how to fix them can help you narrow it down.

Safety First

Before you touch anything, turn off the power. Unplug the dishwasher or switch off its circuit breaker. Water and electricity are a risky mix.

Also shut off the water supply before you disconnect any hose. Keep a towel and a shallow pan handy for drips.

Step 1: Check the Cycle Settings

Start with the basics. Many "no water" problems turn out to be a setting.

• Make sure a wash cycle is actually selected.
• Check that Delay Start isn't on.
• Turn off Control Lock or Child Lock if your model has one.
• Press Start again after you shut the door.

If the display shows an error code, look it up in your owner's manual. It may point straight to the problem.

Step 2: Check the Door Latch

Your dishwasher won't fill if it thinks the door is open. A safety switch stops the water until the door is fully latched.

Close the door firmly and listen for a click. Look at the latch and the strike on the tub. If either is bent, cracked, or loose, the switch may not engage. A worn door switch is a common cause, and it's usually a quick repair.

Step 3: Check the Water Supply Valve

The shut-off valve sits under the kitchen sink. It feeds water to the dishwasher. If it's closed or only partly open, the dishwasher gets little or no water.

• Find the valve on the supply line under the sink.
• Turn the handle so it's fully open. It should line up with the pipe.
• Run the hot water at your kitchen sink for a minute. If the water is weak, your home may have a pressure problem.

If it's been very cold and the supply line runs through an unheated space, the line may be frozen. Let the area warm up before you try again.

Step 4: Look for a Kinked Inlet Hose

The inlet hose carries water from the valve to your dishwasher. A kink, a bend, or a squeezed spot can block the flow.

Slide the dishwasher out slightly if you can, or look from the front panel. Check the hose for sharp bends. Straighten any kinks. If the hose is cracked or worn, replace it.

Step 5: Test the Float Switch

Inside the tub, you'll find a small dome-shaped float, usually in a front corner. It rises as the water level goes up, and it tells the dishwasher when to stop filling.

If the float is stuck in the "up" position, the dishwasher thinks it's already full. So it never fills.

• Lift the float gently, then let it go.
• It should move up and down freely.
• Clean away any gunk or food that's blocking it.

If it doesn't move, or the switch under it is faulty, it needs replacing. This is another common part to fail.

Step 6: Clean the Inlet Valve Screen

Most water inlet valves have a small screen that catches grit and mineral flakes. If it clogs, water can't get through.

Turn off the water and the power. Disconnect the hose from the valve and look at the screen. Rinse off any debris. Then reconnect everything and check for leaks.

If you're not comfortable with this step, a technician can do it quickly.

Step 7: Suspect the Water Inlet Valve

If the checks above didn't solve it, the water inlet valve may have failed. This valve opens when the dishwasher calls for water. When the electric coil or the valve itself wears out, it stays shut.

Signs of a bad inlet valve:

• The dishwasher hums, but no water enters
• Very slow filling
• Water that keeps running, or trickles in after the cycle ends
• A valve that looks cracked or corroded

A technician can test the valve with a multimeter. Replacing it is often straightforward, but it involves both water and electrical parts.

Other Causes to Know About

Sometimes the cause is deeper:

• Control board or timer problems. The board may not send power to the valve.
• Low water pressure. Weak flow at home can make a dishwasher fill slowly or not at all.
• Clogged drain or standing water. Water already in the tub can trigger the float and stop new water from coming in.

DIY or Call a Pro?

You can handle the simple checks yourself. That means settings, the door, the supply valve, and the hose.

Call a technician if:

• The float, inlet valve, or control board needs replacing
• You see leaks or water damage
• You smell something burning
• The breaker trips
• You're not comfortable working with water lines or electrical parts

How to Prevent This Problem

• Run hot water at the sink before a cycle to clear cold water from the line.
• Clean the filter and spray arms every month.
• Don't slam the door.
• Check the supply hose once a year for wear.
• Use a dishwasher cleaner every few months to cut buildup.

Dishwasher Not Getting Water FAQs

Q: Why is my dishwasher not filling with water?
A: Common causes are a closed supply valve, a faulty door latch, a stuck float switch, or a bad water inlet valve.

Q: How do I know if my dishwasher water inlet valve is bad?
A: Signs include humming with no water, slow filling, or water that keeps trickling in. A technician can test it.

Q: Can a float switch stop a dishwasher from filling?
A: Yes. A stuck float tells the dishwasher it's already full, so no water comes in.

Q: Why does my dishwasher hum but not fill with water?
A: The motor may be running while a clogged or failed inlet valve blocks the water.

Q: Is it worth fixing a dishwasher that won't fill?
A: Often yes. Parts like the float or inlet valve are usually affordable to replace on a newer unit.

A dishwasher not getting water is rarely a disaster. In most cases, the cause is something small. A closed valve, a door that didn’t latch, a kinked hose, or a stuck float can all stop the water. Start with the easy checks, work your way down the list, and you may fix it in minutes.

Some problems, like a failed water inlet valve or a faulty control board, need a trained technician. Don’t force it. Working with water lines and electrical parts can go wrong fast, and a wrong move can cause leaks or damage.
