PICTURE E1-4: NTC resistance to be measured must be around 5.6K ohm at 25 degrees (Display board) The measured value is NTC resistance value. Does it show approx. 5.6K under 25°C temperature? (Picture E1-3) (There should not be open circuit/short circuit) No Open the rear cover of the machine. After removing the NTC socket on the heater, measure the NTC value directly on the NTC. (Picture E1-4) Important Note: In case of NTC open circuit/short circuit and heater open circuit on the washing machine, i.e. if there is E1, E2 or E3 error, machine performs cold washing and ends the programme without the heater activated. Yes As the value measured on the control board socket is wrong, cabling is improper; check it. There should not be any loose or defective cable or socket. INFORMATION: NTC resistance decreases as its temperature rises. For example, it shows a resistance of 9500 Ohm under 10°C, and 1700 Ohm under 50°C. These values are not faulty.

PICTURE E5-2: Pump resistance is being measured on the pump connector Is there 220 VAC voltage? No Replace the control board. Yes Switch off machine and remove its front wall in order to check its pump coil resistance. There should be approx. 180 Ohms between the two pins (purple-green) of the pump connector. Check Picture E5-2. There should not be any open circuit or short circuit Is the pump resistance correct? No Replace the pump. Yes Repair the cables and/or cable terminals.

Picture E17-1: Valves and drawer hose connection * Machine failed to spin. * Time extended. * Although I did not select extra rinse, machine performed another rinse cycle. E17 Is there an E17 error? Yes *Programme finished without spinning due to foam. PREWASH VALVE Check if the main wash and prewash valves are correctly connected to the related compartment of the detergent drawer. If prewash is selected, water fills in the prewash compartment when the machine takes in first water. If prewash is not selected, first water is taken from the main wash compartment. Is it so? (Picture E17-1) Yes Explain the customer the following antifoam measures. Foam formation reasons and prevention methods 1) If you add detergent in the prewash compartment although you have not selected prewash, detergent will be taken from this compartment while rinsing the laundry and cause foam formation. 2) You should use detergents designed for automatic machines. 3)Laundry can remain with detergent as a result of using excessive detergent. You should try to use only adequate amount of it. 4) Keep your detergent in a closed and dry place. 5) You should use less amount of detergent than ever for your lacy laundry. 6) You should not use too much softener. No MAIN WASH VALVE Correct the water intake hoses. Is there an E18 error? * Machine failed to spin. * Time extended. Yes E18 Explain the customer the following methods for preventing unbalanced load. Reasons of ending the programme without spinning as a result of detecting unbalanced load *Programme finished without spinning due to unbalanced load. 1) When you use the machine with less laundry, laundry may pile up on one side of the drum. There is the risk of damaging the washing machine when it is operated at higher speeds with unbalanced load. Therefore, when the unbalanced load in the machine exceeds the limit value, the machine will not spin for safety reasons. 2) The possibility of piling up of laundry at one point in the drum will be higher when the machine is operated with a single pullover, bathrobe or towel. Avoid washing such laundry as one piece as much as you can. Is there an E20 error? *Machine door won't open. Yes Replace the solenoid door lock Does the error persist? E20 Yes Replace the main board *Door solenoid triac or relay short circuit Start a programme again and check. Is there an E28 error? * Machine does not function. *Machine does not take in water. Yes Replace the solenoid door lock Does the error persist? E28 Yes Replace the main board *Door locked signal (zero cross) cannot be received Start a programme again and check. Is there an E29 error? * Programme ended in a longer time. * Machine did not heat well. Yes E29 Measure the supply voltage. Is the operating voltage lower than 150 VAC or higher than 290 VAC? *Operating voltage out of limit Yes Brief the customer about operating voltage of the product and making necessary changes on the electrical installation to enable the customer to use the product within the specified operating voltage range. Programme selection key does not select, or the selected programme is not the same as the running programme, or Some programmes cannot be selected. For example, machine takes in water although spin is selected Replace the control board Picture 1: Valves socket connection Machine takes in water from the wrong detergent compartment Are the valves connected to KN18 - Prewash (Blue), KN18 - Main wash (red) (Picture-1) terminals? PREWASH VALVE MAIN WASH VALVE Fix the connections. Check with a function test. Picture 2: Valves drawer hose connection Yes Perform a function test on the machine to check compartments of the detergent box. (Picture-2) Check if there is 220V AC on the relevant valve during the test steps PREWASH VALVE DRAWER HOSE INLET Yes Is there 220VAC voltage on the relevant valve during water intake from each compartment? No Replace the control board Replace the valve MAIN WASH VALVE DRAWER HOSE INLET Is the machine continuously blowing the fuse and is there not an error code? Make sure that water is not coming upon the control board, motor, heater, pump, door lock or valves of the machine. Yes Remove the heater sockets to check if there is short circuit on the heater. Replace the heater. Yes Is there short circuit on the heater? No Fix the cabling. Yes Check the cabling of the machine; is there any stripped, broken, burnt or melted cable? Run the machine one more time; can it operate for a while without blowing the fuse? Yes During the function test, check which component blows the fuse. Remove the connected socket terminals of the part that blows the fuse and perform a short circuit check. Replace that part if there is short circuit. If not, recheck the cabling. No Is there any trace of burning-blowing on the control board? Yes No Does the machine continue blowing the fuse? Yes Replace the control board C7S Bluetooth setup Add / Remove Products Select a product Which product do you want to add? There is no product in your Homewhiz account or network.
