Oven Convection Fan Not Working? 6 Causes and What to Do
A convection fan that will not spin is usually a failed fan motor, a seized blade, a door switch or a relay on the control board. Here is how to narrow it down.
Read the guideWhy is my dishwasher so loud?
A louder dishwasher usually has something caught in the pump or filter, a spray arm hitting a dish, a worn wash motor bearing, a failing drain pump or a loose part. Grinding points to debris in the pump. Squealing points to the motor. Rattling or banging is often loading. Knocking at the start of a cycle is often the water valve and pipes.

Listen for when the sound happens. A noise during the wash points to the wash motor or spray arms. A noise only while draining points to the drain pump.
What do the common sounds mean?
| Sound | When | Likely cause |
|---|---|---|
| Grinding | Wash or drain | Glass, seeds or bone in the pump or chopper |
| Loud humming, no water moving | Drain | Stuck or failing drain pump |
| Squealing | Start of wash | Dry wash motor seal or worn bearing |
| Rattling or banging | Wash | Spray arm hitting dishes, or loose dishes |
| Knocking or thud | Filling | Water hammer from the inlet valve |
| Buzzing | Any time | Inlet valve, fan or a loose panel |
What can you check yourself?
- Turn the dishwasher off and switch off the breaker before reaching inside.
- Pull out the bottom rack and remove the filter. Look for glass, seeds, bones or labels.
- Spin the spray arms by hand. They should turn freely and not hit tall items.
- Reload so pots and baking sheets do not block the arms or the soap cup.
- Check that the kick plate and any panels are tight.
- If it squeals on the first run after a vacation, run a short cycle; a dry seal often quiets down.
Clean the filter every few weeks. Mountain View's hard water adds scale that traps food bits; our dishwasher hard water guide explains how to deal with it.
Loud grinding, a burning smell or water on the floor? Turn it off and call now for dishwasher help in Mountain View.
When should you call a technician?
Call if grinding continues after you clean the filter, if the dishwasher hums but will not drain, if it squeals on every cycle, or if you smell burning. These point to a pump, motor or bearing that needs testing or replacing. Most dishwasher repairs in Mountain View run about $150 to $400 with parts and labor.
A drain pump that hums but does not move water often leads to standing water; see dishwasher not draining. Water under the door or on the floor is a separate problem; read dishwasher leaking. Our dishwasher repair service covers all major brands.
Check the CPSC list of product recalls if your dishwasher model has a known motor or wiring problem.
