Dishwasher problems can be frustrating, especially when they disrupt your daily routine. If your dishwasher isn’t filling, draining, or leaking water, you might wonder whether to call a plumber or an appliance repair specialist. The right choice depends on the issue. Plumbers handle water supply, drainage, and leak-related problems, while appliance technicians focus on mechanical and electrical issues. Understanding the cause of the problem can help you decide who to call.
Here's What We Have Covered In This Article
1. Can a Plumber Fix a Dishwasher?
Yes, plumbers can fix dishwashers—but only for water-related problems. Since dishwashers rely on a steady water supply and proper drainage, issues like clogs, leaks, or low water pressure often require a plumber. However, if the dishwasher won’t turn on, isn’t heating water, or has a mechanical failure, an appliance repair specialist is the better choice.
2. Common Dishwasher Problems That Plumbers Can Fix
Plumbers specialize in fixing water supply and drainage issues. Here are some common dishwasher problems they can help with:
Clogged Supply Line
Dishwashers need a steady flow of water to clean properly. If the water supply line is clogged with debris, kinked, or blocked, the dishwasher won’t fill correctly. A plumber can inspect and clear the blockage to restore water flow.
Drainage Problems
After the wash cycle, the dishwasher should drain all dirty water. If water remains at the bottom, the issue might be a clogged drain hose or a blocked kitchen sink. Plumbers can clear blockages and repair damaged drain pipes to ensure proper drainage.
Leaking Water
A leaking dishwasher can cause serious water damage. If the leak comes from underneath the appliance, a plumber can check for damaged pipes, faulty water supply connections, or a broken drain hose.
Low Water Pressure
If dishes come out dirty, the dishwasher might not be getting enough water. Low water pressure can result from plumbing issues like pipe blockages or a faulty shutoff valve. A plumber can inspect the home’s water supply and fix any issues affecting water flow.
3. When to Call an Appliance Repair Specialist Instead
If the problem isn’t related to water supply, drainage, or leaks, an appliance repair technician is the better choice. Here’s when to call them:
Electrical and Wiring Issues
If the dishwasher won’t turn on or respond to button presses, the issue might be with the wiring or control board. Plumbers don’t handle electrical work, so an appliance repair technician is needed.
Heating Element Malfunctions
Dishwashers heat water to clean dishes effectively. If the water stays cold or dishes come out greasy, the heating element may be faulty. This is an appliance-related issue that requires a technician.
Mechanical Failures
If the dishwasher makes unusual noises, fails to spray water, or stops mid-cycle, a technician can diagnose and repair motor, pump, or sensor problems.
4. How to Know Who to Call
If your dishwasher isn’t working, a few simple checks can help determine whether you need a plumber or an appliance technician:
- Check for water flow – If there’s no water entering the dishwasher, the issue might be a clogged or damaged supply line (call a plumber).
- Look for standing water – If dirty water isn’t draining, a blocked drain hose or kitchen sink might be the cause (call a plumber).
- Test the controls – If the dishwasher won’t start, respond to buttons, or makes strange noises, it’s likely an internal electrical or mechanical issue (call an appliance repair technician).
- Feel the temperature – If the dishwasher isn’t heating water or drying dishes, the heating element may need repair (call an appliance technician).
By checking these basic signs, you can save time and money by contacting the right professional from the start.
5. Can Plumbers Install Dishwashers?
Yes, plumbers can install dishwashers. Since dishwashers require a water supply, drainage, and proper connection to your home’s plumbing system, hiring a plumber ensures everything is installed correctly.
A professional plumber will:
- Connect the dishwasher to the water supply and ensure proper flow.
- Secure the drain hose to prevent leaks and backflow.
- Check for any plumbing modifications needed, such as installing a shutoff valve.
Poor installation can lead to leaks, water damage, or drainage issues. A plumber ensures the dishwasher is installed correctly, preventing costly repairs down the line.
6. Cost of Hiring a Plumber vs. an Appliance Repair Technician
The cost of fixing a dishwasher depends on the type of problem and who you hire.
- Plumbers typically charge by the hour, with rates ranging from $75 to $150 per hour, plus parts. Common plumbing fixes like clearing a clogged drain or replacing a supply line are usually on the lower end of the cost spectrum.
- Appliance repair technicians may charge a flat diagnostic fee, usually between $75 and $150, plus labor and parts. Repairs involving electrical components or replacing internal parts like the pump or heating element tend to be more expensive.
Factors that affect the cost:
- Type of repair needed – Plumbing issues tend to be less expensive than major appliance repairs.
- Parts replacement – The cost of new components like a pump, heating element, or control board can increase the total price.
- Urgency of service – Emergency repairs or same-day service may come with an additional fee.
Getting a quote upfront from the right professional can help avoid unexpected costs.

FAQs About Dishwasher Plumbing
Is a dishwasher a plumbing issue?
Yes, but only in certain cases. A dishwasher is connected to your home’s plumbing system, so issues like clogged drains, water supply problems, or leaks fall under plumbing. However, if the problem is electrical, mechanical, or related to internal components, an appliance repair technician is the better choice.
How much does a plumber charge to put in a dishwasher?
The cost of installing a dishwasher varies, but plumbers typically charge between $150 and $500 for installation, depending on the complexity of the job. If modifications to the water supply, drain lines, or cabinetry are needed, the price may be higher. Getting a quote upfront helps avoid unexpected costs.
What is the most common problem with dishwashers?
One of the most common dishwasher problems is drainage issues. If the dishwasher isn’t draining properly, it may be due to a clogged drain hose, a blocked kitchen sink, or a faulty drain pump. Other frequent issues include water leaks, clogged filters, and heating element malfunctions that prevent dishes from getting fully cleaned.
Does a plumber need to replace a dishwasher?
A plumber can replace a dishwasher, but it’s not always necessary. If the replacement involves only disconnecting and reconnecting the water supply and drain lines, a plumber is the right choice. However, if the installation requires electrical work or adjustments to the cabinetry, an appliance technician or handyman may be needed.
