The dishwasher is not cleaning the plates and glasses as should, leaving a lot of residue on everything

The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers plates and make sure that the outlet pipe is not kinked, that there is nothing obstructing the pipe or the pump or selector valve. If possible back flush through the outlet pipe and try draining the machine once more before using it again.

check the water connection that goes to the machine, if there isnt enough water getting into the machine then it dosnt clean as well.

the spray arms are not rotating check they spin freely if they do remove them and clean any residue food deposits blocking holes for water spray.

Hi Julie,

The sprayer arms may need replacing.
