As your local appliance technician serving Bethesda, Gaithersburg, Rockville, and surrounding Maryland areas since 1945, Bettar Services has seen it all when it comes to dishwashers. Whether you're troubleshooting a problem, deciding between repair or replacement, or shopping for a new model, this comprehensive guide has you covered.

Dishwasher Does Not Start? Here's Why
Before calling for service, check these common issues:
1. Power Supply Issues
- ✓Check the circuit breaker: Reset if tripped
- ✓Verify outlet power: Test with another appliance
- ✓Inspect power cord: Look for visible damage
- ✓Ensure door is latched: Dishwashers won't start if the door isn't fully closed
2. Door Latch Problems
The door latch must be fully engaged for the dishwasher to start. If the latch is broken, misaligned, or the door switch is faulty, the control board won't receive the signal to begin the cycle.
DIY Fix: Check for obstructions preventing the door from closing completely. If the latch mechanism is damaged, contact a local appliance technician.
3. Control Panel Malfunction
If buttons are unresponsive or the display is blank, the control panel may need resetting or replacing. Sometimes, a simple power cycle resolves the issue.
Try this: Turn off the breaker for 5 minutes, then restore power. If this doesn't help, the control board likely needs professional repair.
4. Thermal Fuse Blown
The thermal fuse protects your dishwasher from overheating. If it blows, the dishwasher won't start at all. This requires professional diagnosis and replacement.
Professional service needed: Testing and replacing thermal fuses requires technical expertise and proper tools.
5. Timer or Motor Issues
A faulty timer or motor can prevent the dishwasher from starting. These are complex components that typically require professional diagnosis and repair.
Common Dishwasher Problems & Solutions
Poor Cleaning Performance
Causes: Clogged spray arms, dirty filter, hard water buildup, or wrong detergent
Solution: Clean spray arms and filter monthly. Use rinse aid. Check water temperature (120°F minimum).
Water Not Draining
Causes: Clogged filter, blocked drain hose, or faulty drain pump
Solution: Clean the filter and check the drain hose for kinks. If problem persists, the drain pump may need replacement.
Leaking Water
Causes: Worn door gasket, loose connections, or cracked tub
Solution: Inspect and replace door gasket if worn. Tighten connections. Cracked tubs usually require replacement.
Strange Noises
Causes: Foreign objects, worn pump bearings, or loose spray arms
Solution: Check for debris. Ensure spray arms spin freely. Loud grinding may indicate pump failure needing repair.
Dishes Not Drying
Causes: Faulty heating element, broken vent, or low rinse aid
Solution: Refill rinse aid. Check if heating element works. Ensure vent opens properly during drying cycle.
Soap Dispenser Not Opening
Causes: Blocked by dishes, broken latch, or timer malfunction
Solution: Ensure nothing blocks the dispenser door. Clean around the latch. Replace if mechanism is broken.
Should You Repair or Replace Your Dishwasher?
✓ Repair Makes Sense If:
- • Dishwasher is less than 7 years old
- • Repair cost is under $300
- • It's a simple fix (pump, heating element)
- • You're satisfied with its performance
- • It's an energy-efficient model
➔ Replace Makes Sense If:
- • Dishwasher is over 10 years old
- • Repair cost exceeds 50% of replacement
- • Multiple components are failing
- • It's not Energy Star certified
- • Cleaning performance has declined
The 50% Rule
If the repair cost is more than 50% of a new dishwasher's price AND your unit is over 7 years old, replacement is usually the smarter investment. Our local appliance technicians will provide honest advice tailored to your situation.
