Descripción:
BWIA flight 431 experienced an explosion in the forward galley during climb to cruise altitude. The airplane was substantially damaged, 1 flight attendant received serious injuries and 1 flight attendant received minor injuries. The flight had originated from Miami, FL, about 15:25 and landed back at there around 16,25 the same day.
Examination of the airplane revealed that a water heater, Nordskog model, had over pressurized and exploded. The entire forward galley and the cabin wall to the cockpit was destroyed.

Probable Cause:

PROBABLE CAUSE: "The failure of the water heater relay and the overpressure relief valve to operate properly. In addition, the design of the relief valve was inadequate in that it allowed the O-ring to migrate from its normal position preventing the valve from opening."
