Error code 68


Good Morning Chris, thank you for allowing me to assist you!

Typically error code E68 can indicate one or two issues on your washer. First problem could be that one of the keys (buttons) is stuck. Enter "Function Test Mode" and perform a key test to determine which button is at fault. To perform the "Function Test Mode": Press and hold the START and CANCEL button at the same time for 10 seconds. The trapped key should blink.Carefully free the key and perform the test again. If button is freed but the error code still exists, the electronic control may possibly need replacing. Second issue could possibly be a current leakage to ground on heater or fuse opened. However, I would strongly suggest contacting a professional to the check the resistance of the heating element (should be approximately 14ohms) or the resistance between the ground and both heater terminals. It should be open when heater terminals are disconnected. If the readings are incorrect, heating element could be faulty.

Best regards - Chris

How to put the heat on the aircondition


To get proper heat, keep your temp setting at +5 degree than your temp and also mode in "heat "position. If still noheat, check your heating sensor for closed circuit by an OHMs metre.It it'swith RV, check power to RV.Ifit's with heating element check power to element. If power is there but stillno heat means element defective. Replace new heating element. Thanks.

Only about five minutes of hot water, both elements and thermostats are good?


A] First of all, we know your upper element is working because you have some hot water:
http://waterheatertimer.org/How-it-works.html
It says tank is not overheating.
It says tank is getting 240Volts.
It we know water heater is 240Volts because you have 2 elements.
And it says reset button is not tripped.

B] That leaves 4 suspects:
Suspect 1) Bad Upper thermostat or Bad Lower thermostat: solution replace both thermostats for about 25$. Steps shown in link below.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Suspect 2) Burned out Lower element: solution take out element, clean sediment out of tank, put in new element. Steps shown in link below
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
Suspect 3) Loose wire or connection: solution open covers and remove insulation and look for signs of burning and high heat. Tighten all screws very tight. Replace burned part. Put insulation and covers back over thermostat so thermostat not exposed to cool air which will cause thermostat to misread tank temperature.

C] Before replacing anything, you can test water heater parts and determine exact cause of problem. Testing requires $5 multimeter from Lowes or Home Depot:
Install battery in multimeter.
When test calls for testing voltage, rotate multimeter dial to 240 or 250 or 277 Volts.
When test calls for testing continuity, rotate multimeter dial to ohms (upside down horseshoe symbol is ohms)
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html
After doing 30 minutes of testing, you will be expert in water heaters.

If sediment builds up inside tank, it will reach lower element and burn out the element.
That could be problem.
Restore full efficiency to tank by cleaning out sediment and replacing lower element.

E] More reading to preserve tank and save money long term

We just recently replaced both heating elements in our water heater. Now the water is just barely getting warm and not hot. What's wrong??


Electric water heater if fully repairable by homeowner:

A] First of all, we know your upper element is working because you have some hot water:
http://waterheatertimer.org/How-it-works.html
That says tank is not overheating.
It says tank is getting 240Volts.
It we know water heater is 240Volts because you have 2 elements.

D] You replaced elements for a reason
.
Did you test elements before replacing?
Was tank producing some hot water before you replaced elements?
If tank producing some hot water, then lower element was bad, and upper element was good.

And when you replaced lower element, did you also clean sediment out of tank?

If sediment builds up inside tank, it will reach lower element and burn out the element.
That could have been original problem, and it could be same problem again.

Hot water runs out in 5 minutes it use to last 20minutes


Electric water heater can be repaired by homeowner.

Water heater has some hot water.
We know 3 things for sure:
- electricity is ok
- upper element is ok
- tank does not have overheating problem

Here are the suspects:
- Burned or loose wire
- Upper thermostat not working
- Lower thermostat not working
- Lower element not working

What to do:
1) Turn off power, open water heater covers and look for signs of burned or loose wire, especially on lower element. Burned wire on lower element says lower element is burned out.

2) Test lower element.
Lower elements burn out when sediment builds up inside tank.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-to-replace-water-heater-element.html

3) If wires are ok. And you do not want to test parts, then replace upper and lower thermostat for 25$. If problem persists, replace lower element.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

4) If you want to test thermostats and elements before replacing anything:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

5) When finished, be sure to put insulation and covers back on tank so thermostats don't receive cool air and misread tank temperature. This will prevent overheating of tank that causes red reset button to trip.

Installed new upper & lower elements & thermostats, only top htr works


If original problem was caused by sediment burning out lower element, did you clean sediment out of water heater when changing lower element?
Two element water heaters are 240V.
Thermostats cut power on one hot wire, but 240V circuit has 2 hot wires. So lower element has power at all times coming from the red wire.
1) Use ordinary tester or multimeter set to 240V <> test each screw of lower element to bare metal part of water heater. Each screw should show 120V. If there is no power, then upper thermostat is defective, screw on upper thermostat is loose, or red wire between upper and lower parts of water heater is bad.
2) Remove wires from lower element. Use continuity tester or multimeter set to ohms <> test across both screws of element to see if power travels through element <> if element is bad, then continuity tester will not light up and multimeter will show no ohms. Put wires back on element after test.
3) Start with cold water in tank. Turn on water heater & upper element will turn on. Put ear on side of tank to hear if upper element is heating water. Test #3 screw to #2 screw on low left side of thermostat, should read 240V > Test #3 screw to #4 screw on low right side of thermostat, should read 0V.
Put ear on side of tank. When upper element turns off: Test #3 screw to #2 screw on low left side of thermostat, should read 0V > Test #3 screw to #4 screw on low right side of thermostat, should read 240V. If this test shows 0V and 0V, then upper thermostat is bad. If reading is correct, immediately move to next test.
http://waterheatertimer.org/images/Thermostats-numbered-divided-500.jpg
4) Turn temp on lower thermostat to 150. Using ordinary tester or multimeter set to 240V <> Test across both screws of lower element. If there is no reading, and you know element is good from step 2, then lower thermostat is bad, or wire is bad between lower element and lower thermostat, or wire is bad between lower thermostat and top part of heater.
5) Test across both lower thermostat screws, should read 240V.If this test is good, it means wires are good. Put jumper wire across both screws of lower thermostat, and test lower element again. If element finally turns on with jumper wire, then lower thermostat is bad.

If wire is bad between upper and lower parts of water heater, and water heater has tight-fitting 2" foam insulation, it usually indicates water heater replacement.

My dishdrawer gives a F4 code. What does it mean?


Hi,
The F4 code means that the machine has sensed that the water temperature is not rising while the heating element is energized. There are tests to perform to determine if this condition is caused by a faulty heater plate or the machine's controller. The heater element relay can be energized in the diagnostic test mode, and if the heater does not come on, the heater plate can be tested with an ohm meter. Changing a heater plate is a fairly complex job and you would want to consult a service manual for the proper procedures.
From below website you can learn how to go to diagnostic mode and the reference chart
