Have fault code nh. water not heating. suspect heating element but it is intermittent. Is there a heater relay?

This is usually a failed HEATING ELEMENT or HEATER RELAY. Disconnect power & remove the dishwasher from under the counter.
The HEATER RELAY is located on the right side of the D/W. A metal panel/shield (on the right side) must be removed to gain access for testing.
Testing the HEATING ELEMENT *can* be done from the bottom/front---but is easier if the D/W is placed on it's back---and removing the bottom cover/panel.
In many cases I have seen failed HEATING ELEMENTS or RELAYS on Samsung D/Ws---in homes which had an INSTANT WATER HEATER (AKA: Tankless Water Heater).
This type of Water Heater requires a minimum GALLON-PER-MINUTE of water flow---before it will *heat* the water.
Many dishwashers have a lower GPM flow rate than required---this results in NO HOT WATER at all during water fill.
The D/W heating sytem remains "on" for long periods of time---each time the D/W is used.
Eventually the HEATING ELEMENT or HEATER RELAY fails

Could be: faulty power board (completly or only relay for heating element), faulty wiring between heating element and power board, faulty heating element (interruption, short circuit or current leakage,on some heaters faulty thermal protection).

Depending on the model, the display shows the i60 fault code or the LED end of the program will flash 6 times (only model without display).

1) F9 and F10 appear to be element failure/ Call for service

2) Copy following link for more GE Hybrid Geospring resources:

3) Call GE and they will tell you to call for service:
1-888-443-4394

4) 2009 service manual says you can clear fault codes by pressing Filter, Lock, Vacation button sequentially within 3 seconds. Scroll to clear all fault codes using arrow keys. When that is highlighted, press Filter, Lock, Vacation again.
Others report this does not work, so it may depend on model. Or maybe buttons need to be pressed simultaneously.

5) GE does not want folks working on their own water heater.
Do not buy expensive water heaters you cannot fix yourself.
Average service call for GE heat pump is $400 which helps defeat anticipated savings from buying hybrid.

proceed with common sense and logically, fix it use the Vom or DVOM .God bless you

For this error code you need to check both the water heater or element and thermistor, basically the washing machine is reporting a fault on the heating circuit with this fault code but it is not capable of identifying exactly where the fault actually lies.
On non-display panel models this fault code is denoted by the lights for 95, 60, 40 and cold being lit or flashing.

• Check water heating element
• Check heater for contunuity,
  
• Check steam heater for continuity usually
  
• Check thermistor or temperature sensor
• Check the thermistor resistance,
  
• Check wiring to water heating element
• Check connections to water heating element and temperature sensor

Check and see if the replaced heating element has the continuity to the coils. If so the fault can be failure of the switch or the contactor/relay for the heater. Also the program controller must activate the relay to supply voltage to the coils. so check this line of supply to confirm.

F08 Heater relay cannot be activated
this can be repaired cheap its part of the main board
If it works fine with the heater off then i would say that fault appears to be element..the readings you get seem okay, put you meter onto megs and check, with wires off if you get electrical leakage between live and earth...Body....of element, it could be element is heating with no water in machine causing it to burn out..this is a problem with this machine
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

there is an intermittant break in the circuit leading to the heater element or at the element. have it checked by a pro..

F-05 error means:-- Water Temperature Sensor Error
If during the water heating step in wash cycle, the water temperature sensor (NTC) value is out of range, or the heating element circuit has failed, the "F/05" error code will be displayed.


TO RESOLVE THE PROBLEM:-- 


Check the Water Temperature Sensor, Heating Element and Element Relay Check connections to the Sensor, Heating Element and Relay

You, my friend, have the dreaded 'blinking clean light.' This means that the electronic control has detected that for three consecutive cycles,
1. the heater hasn't come on
OR
2. the water hasn't come into the dishwasher
OR
2.5. the water came in, but wasn't spraying around inside.
OR
3. the heater came on, but the temperature probe did not detect a 3 F degree rise in temp in a certain alotted time. (Is the water supply unusually cold?)

Originally, this fault code could happen if any of these happened just once. Now they program the elec control to wait until the 3rd consecutive ocurrence.
First, let's clear that fault code.
Since you did not mention any unusual sounds, I will assume the water is filling and spraying around inside.
Press 'heated dry', 'normal', 'heated dry', 'normal'. This activated the test cycle, and clears any fault codes. After 10 seconds, press 'cancel'. Open the door and carefully see if the heating element came on. (It should be hot.)
If it did come on, it's an intermittent problem, and could be related to the door switch. Some earlier models would allow the dishwasher to run with only one of the two contacts closed, but the heater would not come on. Be careful to close the door tight each time. They have redesigned the switch (or is it the door latch?) to ensure both contacts get closed.
If the heater did not come on, then you might need (in order of higest to lowest probability) a heater, a heater thermostat, or the electronic control board (heater relay.)
I haven't ever seen a failed temperature sensor, though it is theoretically possible.
You can continue using your dishwasher until it is repaired. Though, you may have to reset the fault code 2-3 times a week.

Good luck!
