Sounds like the controller is the problem. This is the circuit board that has the display and controls on it. You can swing that panel open and try tapping on the white plastic cover the controller is under that. This might get the fan relay to release but you will have to replace the controller it will stick again

More often than not this will be the by-pass and thermal regulator. Both of these are inside the water manifold on the side of the heater. I will usually replace both if one is bad. If one is bad the other can become damaged and the labor and parts to do this are a big part of the job. Also check and see if you have a by-pass on the plumbing going to the heater. This will be a valve bridging the water in to and out of the heater. If you have one it should be 80-90% closed so it forces water through heater. If any of these are bad it will let water go past the heater and the water inside the unit will overheat and turn to steam and with no place to go it just expands and starts banging.

Problem is an obstructed gas oriface. The burners light from the burner closest to the pilot assembly out like a dominoe effect. The explosion is because the gas has to make its way over to the pilot from a further burner thus filling the firebox full of gas before it ignites. This blockage is most commonly from a spider web inside the oriface itself. Pull the burner tray, remove the orifaces from the tray and look through each one cleaning them out with a toothpick from the backside. The orifaces should be threaded on the gas line coming off the gas valve (looks like a silver box inside the front panel)

The connection point is not critical as long as the fireman's switch is connected in series with the safety loop. For instance you may cut a wire connected to the pressure switch and use two wire nuts to connect the wires from the fireman's switch, one to each side of the cut wire.

Thank you for posting your question here on Fixya.com.
Splice the two wires together and try to fire the heater. MAKE SURE THE PUMP IS ON when trying this to avoid any possible damage to the heater. Once you confirm the unit works with the pressure switch bypassed put the wires back until the new part arrives. DO NOT operate the heater with a jumped pressure switch as any disruption to water flow can create a very serious danger to anyone or anything near the heater.
