Normal causes for that would be by-pass valve not in proper position, or defective, allowing cold to mix with hot, or thermostat not touching up against tank properly, or defective. Do you know where that thermostat is?
Look where the black foam cover is, with white letters, below pressure relief valve. One is lettered ECO, other THERM. If you note where the wires go, so as not to mix them up , and pull them off, then peel back the foam cover, you'll see 2 little round discs, that are held against the tank by a small spring. They need to be checked that they are in there properly and are up against the aluminum tank.

If it has the little thermal cut-off in power wire to thermostat (has a little plastic jacket over it) try removing it, and connect female spade from power wire, directly to male spade on thermostat, and see what happens. Also, make sure electrode is positioned in flame good for flame sensing properly.

If this model has a thremo couple you might want to check it. It sounds like that is the problem.

Check for a bad fuse in panel first, then with a 12 volt test light or multimeter, check for power in to switch, as well as out when in on position if it's easy to get to. If not, turn switch on and test for voltage at brown wire to thermostat terminal, that comes from inside at back of water heater from switch inside. If it has cut-out switch in plastic sleeve attached, be sure to check for power on both ends of that cut-out switch. If power only in but not out, replace it. As I said,that brown wire comes from switch, so if no power to it, check at switch. The other brown wire goes back to connector on ignition board. If power is there, turn switch off, take an eraser on end of a pencil and rub contacts on ignition board/module to clean them off, as well as spray electrical cleaner on contacts of connector to make sure you have a good connection. Check all ground connections as well, and if you have 12 volts at brown wire to connector on ignition board but still no spark, replace ignition board/module.
