You should be getting an Error code 37 pump faulty.
37.(00100101) Pump Blocked Error (No change in the water level)
While draining, the water level reading from the pressure sensor has not changed for over 3 minutes. There are three likely reasons for this fault. One is that the drain hose or the pressure switch hose has been squashed or kinked and the pump out rate has been dramatically reduced. The second possibility is that the pump is partially or fully blocked. The third is that the pump is not operating due to Motor Control Module, wiring or pump failure. This fault could also appear if the machine is pumping to an unusually high head of drain hose or into an extended length of drain hose. The fourth possibility is a diverter valve fault or blockage, water level is not altering as the diverter is stuck in the recirculation mode, giving the module the appearance the pump is not lowering the water level.
Primary Source:
Action:1)
Pump System.
Check that the drain hose has not been kinked.
2) Check the length of the drain hose and try to reduce the length if
excessively long. A 39.36in / 1 metre extension hose of the same diameter fitted to the existing drain hose is the maximum allowable length.
3) Check for open circuit windings in the pump. (Note: Pumps are
fitted with a thermal cut-out, which will reset on cooling.)
4) If the basket is empty of water, remove the pump from the pump
housing and check that it is not blocked. Also check the drain hose is not blocked.
5) If the basket contains water, then service the pump from the top of
the machine by removing the top deck and inner basket. Bail out the water, remove the pump cap and hood and clear the restriction.
Secondary Source: Wiring.
Action:
Tertiary Source:
Action:
1) Check the pump harness is connected correctly to the pump. 2) Check continuity of the pump harness.
Motor Control Module module.
Activate the pump by operating the machine in spin mode. Check the pump is rotating. If it is not operating, and Primary and Secondary checks have been performed, then replace the Motor Control Module.

I worked out that code to be 37

If hoses clear and filter not blocked, can only be pump fault

yes there is or was a clog and now the unit is probably in drain mode and wont let in water until leak is dry.

P2 error indicates that the spill reservoir in the base of the unit is full.
Solution:
Move the unit to a location that is suitable for draining water from the unit. Remove the plug in the lower center of the back of the unit and allow the water to completely drain (Remember to replace plug.)
Remember...this is not the water tank on the side. This is the water than can collect in the bottom of the unit. Take it outside and drain it

Empty the water pan. It not sealed so dont slosh it around. Mine did the same thing. Amana rep was an ***. Wouldn't give me an inkling of what to do. So i started to fiddle around. There was a lot of water in it Be careful. I brought mine to the tub and drained it for close to 2 min. Started right back up!

The dishwasher is stuck in drain mode because there is water in a catch leak area underneath, it may have been caused by soap suds over flow or disposal backup. Remove bottom kick plate and vacuum out any water, then run dishwasher again and look for water leaks.

check for restriction in sump. ie remove rotor, push pipe cleaner or similar from filter sump into rotor sump

Check your drain line and/or drain pump. The drain line should have a high loop at the point prior to where it connects to your drainage system in order to prevent drain water from the kitchen sink from back flowing into the dishwasher. In addition, most drain pumps have a small check valve that prevents this water from backing up as well. However, if you have something lodged in the drain pump (i.e., a toothpick) it can prevent the check valve from closing properly. This can cause water to back up into the dishwasher. You mentioned that the water will not drain. Is the drain pumping runnings at all? Please post back and let me know.
