Water Not Spraying

The water is filling, heating and draining but no water is being sprayed up into the dishwasher. There is a hum noise when the water is suppose to be spraying. I am going to replace the pump but not sure how to access it. Can I do it from inside the tub or do I need to remove the dishwasher from the cabinet? Is there a repair manual/schematice online that I can look at?

Thanks for your help.

Hi,
Sounds like you have a newer sytle design. There are probably two pumps (drain and recirculating) if your unit is draining the I would check the recirculating pump for a obstruction. You will probably need a #15 torque to get into it.
You can access is from the inside for most of it. If not you can access it by taking removing lower panel without removing the whole dishwasher. Make sure you disconnect power first though.
Hope that helps
