We can't get our hot tub to heat. The heater light comes on but the heater still won't heat.


heating elements are resistors that get hot
one end will have 115 volts but the other end should be considerable less because the resistance of the heating element drops the voltage
if you used a ohm meter you should be reading a resistance of 500-1000 ohms for a good heater element but with your readings , there will be no resistance so the element is faulty

How do I test heating elements and identify leads


The heating elements can be tested for continuity using a voltage meter. Continuity is "continueness". If no continuity, then you need to replace the elements. They are sold based on the voltage and amperage of the water heater. That information is available on the information tag on the side of the tank.

Hello - I have a 6-7 yr old Whirlpool EnergySmart 50 gallon 5500 watt water heater. (Two control boards fried and were replaced free). Symptom now is not enough hot water. No 'error codes' are blinking...


1) Residential water heaters are non-simultaneous. Only one element works at a time.
Upper element comes on until top of tank is heated, and then lower element is switched on until lower part of tank is heated. Lower element keeps tank hot during standby hours
http://waterheatertimer.org/How-it-works.html

2) Typical Whirlpool energy smart has 4500Watt elements. Look at label on side of tank
If both elements were ON, that would draw 9000Watts or 37.5 amps, requiring 50 amp breaker and 8 gauge wire. V x A = Watts.
All dual-element tanks are 240V.
Whirlpool energy smart requires 10 gauge wire and 30 amp breaker so electronics are not starved during operation. If your wire or breaker are undersized, that is suspect for repeated failure.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

3) Typical electric water heater heats 21 gallons per hour. First hour delivery is higher since elements heat water as you use it. Overall however, electric water heater cannot re-heat as fast as gas because gas water heater burner carries more BTU punch per minute than electric element. Gas heats about 41 gallons per minute, with higher first hour delivery.

4) IF YOU HAVE OLDER energy smart and installed newer board, then you could have non-simultaneous operation is reversed so that lower element comes on first.

5) Another potential problem is that you have sediment inside tank and that is reducing efficiency of lower element.

What cause the water heater to take more than an hour to heated up and unable to last longer. Usually its take about 15 min. to heat up and can last longer.


'Rheem 81VP15S point of use' is a single-element, 15 gallon, 120V electric.
Other 'point-of-use' sizes range from 2-1/2 to 6 gallon to 20 gallon.

Electric water heaters have 2 parts: thermostat and element. One is not functioning correctly. Most likely the element caused by sediment build-up.

How to determine if tank has element or thermostat problem:
Do not turn off water going into tank. Put hose on drain valve. Open drain valve. Does water come out like open spigot? If water does not flow, then heater is likely clogged with sediment.

Solution 1: If water flows out like a spigot, the thermostat is probably bad. Read: How to replace thermostat.

Solution 2: Water does not flow, so element is surrounded by sediment build-up and cannot heat water. You need to clean out tank with shop vac, and put in new element ... plan full day and 3 trips to hardware store. Simply draining tank will not remove sediment. Sediment is chunky and will not come out voluntarily.

Buy element before starting:
-Turn off electricity
-Open cover on side of tank, remove insulation (these have to be put back for proper operation of thermostat)
-The are 2 electrical parts >>the element and the thermostat which is located above element
-Element wattage is printed on element and also shows on label on side of tank
-I think Rheem element is held in place with 4 hex bolts
-Take photo of element to hardware store so you have part on hand before removing old element
-If element is 1-1/2' diameter hex type, you need inexpensive element wrench from hardware store + the element

Drain tank and clean sediment:
-Read: To open drain on water heater so water comes out
-Read: How to clean sediment out of water heater

look for a badly connected power line ont he bottom element, or any connection upstream of the power terminals. voltage readings usually drop to that range when you only have one side of the 220v circuit connected.

Installed new thermostats and element and now have no hot water except I have power every where


You need to check the resistance of the Element... and check that the Thermostat is actually switching the power through, when it gets to temperature. Do a continuity test from the P & N, to the Element. usually the Phase comes in to the Thermostat, then through to the Contacts, to the "Hot" side, of the Heating Element, & back from the "Other"s side, the "Cold" side of the Element, to neutral. When thermostat is Operated, ON, When it gets to selected temperature it switches OFF, you should have a Resistance, measurable from P & N at mains lead in.
You can figure this resistance out by Dividing the Wattage of unit, by the Voltage this gets the Current, Now we divide that Current, into the Voltage and we get the "Resistance" of the "Load" or Element. This is what you should "See" with your OHMS Meter when you look "In" to the circuit. +/-10% is OK

I can't get 240v across the bottom element. Where should I start? Shouldn't it have 240v across it? I can ground one side of the meter to the tank and can get 120v to each side, but not 240v across the...


If that is indeed so you have a "Short" between Phase and Earth. .. YES one should have the mains Voltage across the Load, But NEVER anything between Phase & Earth. Look think of it all like this. The Phase comes in, to a, say, a switch, from switch, to thermostat, from thermostat, to One Side of the "Load" Element. The "Other side of that "Load" Element then goes to Neutral. Circuit Complete. Two elements, wired in series would indeed split the Voltage, if wired that way. If done like this, but if wired in parallel, then, again Both would have One End, connected to Phase, & the "Other" side(s) would go to Neutral. Thus the circuit is complete. Some setups are more complex, and use two elements. but essentially all the same. The elements could be wired in series or parallel, depending on current draw/resistance. The Phase is the wire always "Broken" and the Neutral is always "Common".
BE CAREFUL.

Take off front cover, on the top of the two cylinders in there (the heating system) there will be a small red button. That is the Safety Thermal Cut out, depress that red button. It is similar to a circuit breaker. If the red LED comes on when you turn on hot water at a sink then that was the problem. I have on that trips periodically. Its annoying but not enough to replace the part yet. Good luck.

How do you wire a thermostat to the heating element and then to power . it is for a water tank in a truck that plugs into 110.


you have to put the thermostat in line with the hot side of power supply then to heating element nuetral connects to element directly

Heating elements do not operate together


That's how they work. First you need to know that cold water goes into the tank near the bottom (because of the "dip tube" inside the tank) and hot water is taken out at the top. Also hot water naturally rises.
so... when the tank is full of cold water the top element will come on and heat up the top 1/3 of the water then the bottom element will come on and finish heating the rest of the tank
