Kenmore smart wash- doesnt seem to have good water flow

My dishwasher has started making a loud buzzing noise and doesnt seem to have good flow of water. Some water definately does spray inside..but dishes don’t get clean and soap never fully dissolves…/ I can’t live without my dishwasher!! Help!!! Any ideas or suggestions would be wonderful! Thanks!:smiley:

ps. the buzzing noise occurs when i normally would hear water sloshing around…but no water can be heard

ooops the model # is 66517362300
