Comfee Mini table top dishwasher

The dishwasher is a table top dishwasher. It has its own tank as well.

The issue which I have is that the spray cycle is not performing well. When I start it , it sprays and go idle. Sometimes I start and stop it goes spray again. The spray is not continues. It drains fine fills up fine . The spray rod is spinning and water is coming with enough water .

No error code and ester is not very warm .

What would be the issue
