Is this worth fixing? And would it be easy for me to fix?
Like, is there a drain or filter that is clogged.
I’m happy to try but don’t want to waste my time.

Thanks for any help you can give me.
This dishwasher is probably about 14 years old.

What is the water level during the wash cycle?

How hot is the water inside the dishwasher?

Hi - this unit is in my rental house. I emailed the tenant and she said that the water is steamy, but she doesn’t know about the water level and will run an empty load to check it out.

My renter said that the water is 1/4 to 1/3 inches deep.
I also read that a solution is adding vinegar to the cycle. Will this help and when would you add it?

Thanks!
