Lft114 dishwasher does not get hot and start and wash button flash

does it need salt? or finisher?

Probably the washing pump does not start.
This could be a problem of the pump or the control unit.

Good luck!

Instructions

1. Wait approximately 90 seconds for the light to turn off if the "Start/Reset" indicator light flashes. Press the "Start/Reset" button to restart the wash cycle.
2. Close the dishwasher door and move the latch to the locked position if you hear a beep once every 30 seconds when the dishwasher should be operating. The dishwasher will not operate if the door is open.
3. Turn on the hot water faucet and feel the water to check if it is hot. Wait for the water to warm up before running the dishwasher if the water is not hot. Check that you have proper water pressure and wait for the pressure to return to normal if it is low. Your dishes may not come out clean if the water is not the correct temperature or if you have low water pressure.
4. Move the dishes on the racks so that they do not block the detergent dispenser or washer arms on the bottom of the machine. The dishes will not come out clean if they block the detergent dispenser or the washer arms.
5. Load the proper amount of detergent in the dishwasher if you find spots or film form on your glasses. If you have hard water, use a rinsing product such as Jet-Dry in the dishwasher to clean the spots or film. If the problem persists, wash smaller loads of dishes.
6. Add only automatic dishwasher detergent to the dishwasher if you find excessive suds in the tub after running a cycle. Measure out the proper amount of detergent.
7. Press the "Heated Dry," "Hot Start," "Hot Wash" and "Added Heat" buttons, if you find that your dishes are not fully dry after a wash cycle completes.
8. Press and hold the "Heated Dry" button on the dishwasher for approximately three seconds if the control pad does not respond to button presses. This is the child lock that prevents unwanted use of the dishwasher.

The blinking "clean light" is a common problem with some of the Kenmore and Whirlpool models dishwashers.
The problem is usually attributed to water supply temperatures being too low when filling.

Apparently, there are some issues with the temperature sensing circuits in some dishwashers that causes an error code to be generated if a certain water temperature is not achieved in a specified time interval (this time may differ between models).
There is a reset sequence that you can try to clear the fault.
Push the NORMAL WASH then HEATED DRY buttons in that sequence two to three times.
The unit will enter diagnostics mode, but can be stopped by pressing the CANCEL button.
This will clear any existing faults and should return the dishwasher to normal operation.

To keep the fault from returning, it is recommended that you run your hot water faucet in the kitchen until it runs hot BEFORE you start the dishwasher.
This will heat the water in the supply line for the dishwasher (most dishwashers are fed from the kitchen sink supply line).

The theory is that if you fill the dishwasher with hot water from the start of the wash cycle instead of the cool water that is normally in the lines (especially if you have a hot water tank located far away from the kitchen), this should satisfy the requirements of the temperature sensing circuits.
If the fault reappears, there should be a tech sheet located inside the lower panel under the door that explains what the fault is.
The flashing light will be a series of flashes, followed by a pause.
If you indeed have a component problem, it will depend on the number of flashing lights in the sequence.
Refer to the tech sheet to determine WHAT component is affected and how to troubleshoot.

means either Heater Open circuit or NTC thermistor detached from casing. so check resistance of heater.. if ok then pcb required...

Press the normal wash then heated dry buttons in the same sequence two to three times. The unit will enter diagnostics mode, but can be stopped by pressing the cancel button.It will clear any existing faults and makes the dishwasher to operate normally.

To prevent the issue from recurring, run your hot water faucet first to ensure that hot water is present in the entire supply line before starting the filling.

try this, I was researching and found that this solution worked. While all the lights are blinking, close the dishwasher door and let the machine run through the cycles. This actually happens pretty fast. Then it will stop and quiet down and all the blinking lights will shut off. Then just press the buttons you want and hit start and the machine will start. The time it takes for the blinking light to shut off is about 1 to 2 minutes. It worked for me.

If this is a blinking "clean light", this is a common problem with some of the Kenmore and Whirlpool models. I believe the problem is attributed to water supply temperatures being too low when filling. Apparently, there are some sensitivity issues with the temperature sensing circuits in some dishwashers. There is a reset sequence that you can try to clear the fault. Push the NORMAL WASH then HEATED DRY buttons in that sequence two to three times. The unit will enter diagnostics mode, but can be stopped by pressing the CANCEL button. This will clear any existing faults and should return the dishwasher to normal operation.
