Every time the lights on your dishwasher blink, this indicates the existence of a problem. This is what happens in old models of dishwashers that have no display panel. You can still tell what the error codes are by examining the combination of the blinking lights. However, you need to be careful about interpreting error codes, considering that the dishwasher blinks because of regular use.
You should only consider the regular blinking as an error code if the washer fails to work properly. To fix the error, you only need to make a slight adjustment and get things working normally again. This article explains the variations interpretations that can result from blinking lights and possible fixes.
Express 60 – Incorrect Water Pressure and Temperature
When the water pressure and temperatures are incorrect, the dishwasher will signal the error. Correct it by:
- Ensuring that the water pressure and temperatures match the requirement of the water
- Avoiding the use of floodgate hoses because they are incompatible with Samsung dishwashers
Adjust the Pressure Switch To Chance Water Pressure
If you’re still getting the express 60 error code, then you should try and adjust the pressure switch on your dishwasher. Doing this should fix the temperature on your dishwasher and get rid of the error.
1. Turn off the water supply and electricity. The water supply can be turned off under the sink using the spigot handle. You’ll need to turn it as far to the left as possible then test that you’ve done this correctly by turning on the water in the sink. You can also turn off the electricity by disconnecting the electric cord. You can also cut off the power by throwing the switch to the kitchen in your breaker box.
2. Remove the access panel to your dishwasher. The access panel is located on the pull. You’ll need to pull the dishwasher out from the wall to do this properly.
3. Look for the water heater. It looks like a long tube with a box attached to it. You should notice it pretty easily as the only other items beneath this panel are the pipes and the pump. You’ll also notice the pressure switch which is a round pipe that threads into the heater itself. The top will be facing you when you have removed the panel.
4. Remove the cover on the pressure switch. You can remove the cover by unscrewing the cover in a counterclockwise motion. You’ll need to clamp on your locking pliers and turn to unscrew it. Below this cap, you’ll notice the pressure switch adjustment screw.
5. Unscrew the pressure switch adjustment screw. You’ll need to insert your flat-bladed screwdriver into the adjustment screw and turn it clockwise to reduce the pressure on the dishwasher nozzles. Turning it counterclockwise increases the pressure to the nozzles. If you are turning it counterclockwise, don’t unscrew too much because you might end up dealing with a leak in the fixture. Make a half turn first and then check the pressure by running a cycle to see if everything gets cleaned.
6. Reassemble the dishwasher. Once you have adjusted the switch, put the cap back on, screw the access panel back into place and push your dishwasher back into its alcove. Now, you are ready to give your adjusted dishwasher a try.
Contact the support center for further assistance if after doing this, the error still occurs.
Test If Thermostate Is Bad
The thermostat in your dishwasher is a resistor that changes the resistance depending on the temperature. They’re used in your dishwasher because the resistance at different temperatures in your dishwasher is known therefore your dishwasher can know when certain temperatures inside are reached.
| Temperature °C
|
Resistance Ω
|
To test if the thermostat is bad, you need to check all the connections to the dishwasher sensor and to the board to make sure that they haven’t come loose. It’s unlikely that anything would’ve come loose but it’s always worth checking if there’s a bad connection. You can use a multimeter (view on Amazon) and set it to ohm to measure the resistance on the thermistor sensor on your Samsung dishwasher. When you test the sensor, the resistance drops as the temperature rises. If you’re getting inaccurate readings, then likely to be faulty.
Auto and Express 60 – Panel Detects a Stuck Button
This is an indication that there is a stuck button that the panel has detected. To fix it:
If your panel deters a stuck button or none of the buttons that you’re trying to touch are not working, then you can reset the touchpad. Once the touchpad has been reset, then the auto and express 60 error should disappear. You shouldn’t rule out the chance of error codes being the cause of the touchpad fault.
To reset your Samsung dishwasher’s touchpad, you should unplug the dishwasher and wait for a while so that the electrical charge is removed. Touch every button on the machine to identify the one that has malfunctioned Once unplugged, plug it back in to see if the touchpad is working. This is the fastest way to reset your dishwasher’s touchpad to get the buttons to start working again. Before turning the dishwasher back on again, make sure to leave the dishwasher unplugged for a couple of minutes before you turn it back on. This’ll ensure that the electrical charge has gone. If the error still recurs, call the support center for assistance.
Heavy and Express 60 – Unable to Heat
The dishwasher must heat the water in the washer for it to operate properly. If this does not happen with your dishwasher, then you need to request service by calling the customer support desk. A qualified technician needs to diagnose and fix the error.
Before you jump to any conclusions, you need to make sure that the heavy and express 60 error code you receive is accurate. You may get this code by mistake so it’s best to make sure. You need to unplug your dishwasher and leave it unplugged for 10 to 15 minutes. After this time period, try booting your dishwasher back up and check if the error code has gone. If the code doesn’t show up again, then the issue is fixed. If the codes still show up, then there’s a problem with your heating element that’s not allowing your dishwasher to heat up.
There are a few reasons why your heating element will be malfunctioning with the most common one being issues with your water heater. If your water heater is tankless, then the minimum flow rate might cause problems for your dishwasher – that’ll cause the heating systems to activate but your dishwasher still won’t be able to get any hot water. If you run the dishwasher, this could cause the heater element and heater relay to fail.
If you use an instant water heater aka a tankless water heater, the heating element in your Samsung dishwasher could instantly break down. Instant water heaters need a minimum gallon-per-minute flow and dishwashers have even lower flow rates. So if the dishwasher’s heating system is activated but the device isn’t getting hot water at all. This will happen each time you use your dishwasher and it could cause the heater really to eventually fail.
This will be the most common reason for the error. If you have a tankless water heater, you should take a look at the flow rate of your dishwasher and compare it to the flow rate of your water heater.
To inspect the heater relay, you need to unplug your dishwasher and pull it from underneath the counter. On the right side of the dishwasher, you’ll notice a metal panel. You can remove this and inspect the heater relay for a possible repair.
Auto and Heavy – Too much Water in the Dishwasher
