5 Dishwasher Problems Only Professionals Can Fix Fast

A dishwasher is one of the most convenient kitchen appliances — saving hours of manual washing and ensuring spotless, hygienic dishes after every meal. But when it starts leaking, not cleaning properly, or making strange noises, it quickly becomes a major inconvenience.

While it might be tempting to try a quick DIY fix, most dishwasher problems go deeper than they appear. Incorrect repairs can cause electrical hazards, water damage, or void your warranty. That’s why it’s essential to rely on certified professionals.

At DP Electric Appliance, we specialize in dishwasher repairs across Melbourne, servicing all leading brands — including Asko, Bosch, Miele, Fisher & Paykel, Samsung, Hisense, Neff,  and more. Our certified and experienced technicians provide a comprehensive diagnosis and long-term fixes to ensure your dishwasher operates efficiently for years to come.

Below, we explore the 5 most common dishwasher problems that only a professional technician should handle — and how expert repair services ensure your dishwasher works like new again.

1. Water Leaks That Damage Your Kitchen

A leaking dishwasher isn’t just messy — it can cause serious damage to your floors, cabinetry, and electrical fittings. Water leaks may stem from:

• Worn door seals that no longer provide a tight closure
• Cracked inlet or drain hoses leaking water mid-cycle
• Faulty circulation pumps that allow water to escape

Improper installation or misaligned doors While replacing a seal or tightening a hose may seem simple, leaks are often symptoms of deeper internal damage. Professionals use diagnostic tools to test water flow, pressure points, and seals — ensuring a precise fix that prevents recurring leaks and structural water damage.

2. Dishwasher Not Draining Properly

Pooling water at the bottom of your dishwasher is a common complaint — but it’s rarely just a simple blockage. Common causes include:

• A clogged drain filter blocked by food waste or debris
• A twisted or obstructed drain hose preventing water flow
• A malfunctioning drain pump or solenoid valve

DIY cleaning might temporarily remove residue, but hidden electrical or pump issues often go undetected. Our Melbourne technicians test the entire drainage system — from pumps to valves — to restore smooth water flow and eliminate odor-causing buildup.

3. Dishes Still Dirty After a Full Cycle

If your dishes are coming out greasy or covered in residue, there’s likely an issue with your dishwasher’s cleaning mechanism. Possible culprits include:

• Clogged spray arms not rotating or spraying effectively
• Malfunctioning water inlet valves reducing water pressure
• Faulty detergent dispensers not releasing soap properly
• Low water temperature from a failed heating element

Our experts disassemble key components, clean the internal jets, and run water pressure tests. We also check the inlet valve and heating system to ensure optimal cleaning performance and sanitization.

4. Unusual Noises or Vibrations

A healthy dishwasher should run quietly. If you hear banging, grinding, or rattling, it’s a clear red flag. These sounds can result from:

• Worn-out motor bearings or broken impellers
• Debris trapped in the pump or spray arms
• Loose internal components like racks or fan blades

Ignoring these sounds can cause motor burnout or pump damage. DP Electric Appliance technicians will dismantle the motor housing, remove trapped debris, and replace any damaged parts — restoring a whisper-quiet operation.

5. Dishwasher Not Heating Water

Hot water is critical for killing germs and breaking down grease. When your dishwasher stops heating, you might notice cold dishes, poor drying, or cloudy glassware. This may be due to:

• A burned-out heating element
• A faulty thermostat or temperature sensor
• Wiring or circuit issues within the control module

These are high-voltage components, making DIY repair unsafe. A licensed technician from DP Electric Appliance will safely test the heating circuit, replace faulty elements, and verify that the water reaches optimal cleaning temperatures.
