Tiger hot water heater is not heating up

have you checked heating element.

The heat element probably went bad.

If this is instant heat faucet, then contact manufacturer.
Most these faucets have 1 year limited warranty
Replace faucet?

Try brewing a few pots of white vinegar solution, no coffee in the system.

No attack on this scale is heating element that dissolves when it is possible to disconnect apperaat water heating and draining than doing it in vinegar and let the heat once again connect and then empty and most calcium is removed from apperaat

try to check the heat filament or thermostat heater, maybe it is busted that why it cannot dispense hot water, there water source is came only to one tab and it interconnected inside

I had the exact same problem. I even replaced the first unit with a second unit...because I was sure I hooked everything up correctly. Then I called their support line and and felt very stupid. They asked one question "are you plugging in the Quick&Hot into the same electrical outlet as the garbage disposal"?. I said yes..and the garbage disposal works fine (thinking that this indicates a good electrical outlet). She then said "That outlet works off of a switch so no electricity is getting to the Quick&Hot until the disposal is turned on). Gosh darn it...that made total sense. I then tested this out by plugging an extension cord into a different outlet and it worked fine. Boy...do I feel stupid. Hope this helps.

I would contact the Anaheim Manufacturing Company, that makes the Waste King Quick water heater. You can also go on-line @ www.wasteking.com and check out their site for a solution.
