I'm not sure how to tell if the drain pump is operating. Can you advise how I would know.
By 'condensate tray' do you mean the plastic container that the water collects in while the dryer is on?
Okay - let me see if I can check what you've asked.

Turn off the power to reset either of these situationsI am going to say it is number 2 from your description... and in that case, ask them to repair it under warranty or swap-out the appliance
