Is there an error codes displayed such as E6 on the display?
The first thing to do is check the filter, there is a video here which shows you what to do.
Every whirlpool model is different you may have a flap or you may have a panel across the entire length of the bottom which pulls forward to reveal the filter, have a small bucket and towel to hand to soak up any water, clean the filter and check inside the cavity to see if anything may be inside.
Please let me know how you get on, and I can then advise the next steps.
I just wanted to follow up and check if you required any further assistance?
