Here is a parts breakdown with a wiring diagram

Check your water level after a fill normally just under the heater element
Sound like your unit is cavitating, trying to pump air as it is low on water
Probable causes are something has changed in the house plumbing pressure OR dirty water inlet valve filter screen. Also could be dirty pump filter.
