Hoover Tumble dryer VHC680C-80 Dryer stops and lights to flash what error code is this

by / Friday, 11 October 2019 / Published in

The dryer runs for about 30 seconds then stops and all the lights flash. The display is not digital so i don't know the error code to know what part i need to buy.

You may have a problem with heating system of your Hoover Tumble Dryer VHC680C-80. The cut-out thermostat maybe causing these faults. I have listed a number of common faults with error codes below to assist you in finding the correct procedure to repairing your Hoover Tumble Dryer VHC680C-80.

I have added a video tutorial to assist you in repairing your Hoover Tumble Dryer VHC680C-80. Please be sure you watch the entire video as it will assist you in finding the correct procedure to follow for your repair

Both condenser and vented tumble dryers use very similar heating systems. They usually have one or two thermostat or sensors on the front and one or two thermostats on the back on the heating element.

Thermostat’s fail because of several reasons.

  1.  The machine is interrupted in mid-cycle without letting the machine cool down (opening the door to check washing can cause this)
  2.  Bad air flow through the machine (caused by not cleaning filters etc.) see these videos https://www.how-to-repair.com/help/?s=How+to+service+a+tumble+dry
  3.  Overloading can restrict air flow .

Tumble dryers normally have two thermostats fitted on the heating element housing which is located on the back. These are prime candidates when diagnosing no heat faults on tumble dryers.

One thermostat is normally the cycle thermostat and the other is a safety thermostat this is the one that normally blows when overheating takes place.

  1. AUTOMATIC SEQUENCE OF SELF-DIAGNOSIS (AUTO TEST) AND LIST OF THE ERROR CODES:

D1a) Empty the Dryer and plug it in. The Dryer must be OFF and the door CLOSED. Connect a 20 A/AC reading scale Ammeter, in series to one of the two phases of the mains wire.

D1b) PUSH AND HOLD the START button and  turn the Programs Selector knob  to the position # 3. The Delay Start LED (for Condenser Dryers) or the Acrylic/Synthetic LED (for Vented Dryers) becomes lighted and stays lit with FIXED light.

D1c) RELEASE the START button, then PUSH AND RELEASE IT TWICE, within 2 seconds. The AUTO-TEST sequence is then automatically started.

D2a) For 3 seconds, the Delay Start LED (Condenser Type) or the Acrylic/Synthetic LED (Vented Type) is lighted fixed. Buzzer beeps 2 times for Condenser Dryers and 1 time for the Vented ones. The display visualises ---.

 

D2b) All LEDs are lighted fixed. The BUZZER beeps once.

Should any ERROR be present in the Memory, the machine displays the last ERROR that happened in time. ALL LEDs blink at 2Hz for a number of times equivalent to the Error Number (see the Error Description Table) and contemporarily the display visualises the error number. i.e. In case of Clogged Filter Error = E 7, all LED's blink 7 times at 2 Hz. After the blinking sequence, the LED's are turned off for 3 seconds and then the Error Displaying sequence starts again. This condition is maintained until the moment the Start button is pressed.

Press again the Start button, the buzzer beeps once and the test goes on. N.B. the Start button has to be pressed twice only if there is an error to display.

D2c) All loads are OFF. The Electrically Erasable Programmable Read-Only Memory (EEPROM) checks for any internal error (E6) and checks the conditions of both NTC Temperature Sensing Probes, whose value of resistance must be found within a specific range (can be displayed E5 in case of opened circuit and E14 in case of short circuit). In case of ERROR, the Dryer enters the ERROR MODE (see par. D3).

D2d) All LED's are ON. Motor works clockwise for 3 seconds and Display shows "RIG".

D2e) All LED's are OFF. Motor works clockwise for 3 seconds and the Heater is fed. Ammeter's reading is ~ 11 A. Defective Heater displays E 8.

D2f) All LED's are OFF. Heater is OFF. Motor is OFF. Recycle PUMP is ON for 2 seconds (in Vented Dryers without any pump, only the related relay on PCB is fed).

D2g) All LED's are ON. Motor works counterclockwise for 3 seconds and Display shows "LEF".

D2h) All LED's are OFF. 1 second pause.

D2i) All LED's are OFF. Heater is OFF. Motor is OFF. Recycle PUMP is ON for 2 seconds (in  Vented Dryers without any pump, only the related relay on PCB is fed).

D2l) The LED's of the functions Refresh and Synthetics are ON. The LED's over the buttons are ON. Display shows "GO". Pressing each button, will switch OFF and ON a single LED. Push two times all the buttons in sequence, to test the full functionality of the Power Board. Every time a button is pushed, the buzzer beeps one time.

D2m) Turn the Program Selector back to OFF, to end the Self-Diagnostic Sequence.

Error Phase is a special protective mode that's set every time a critical Error is detected:

  • All LED's flash together at 4 Hz. The buzzer beeps at 1 Hz (1 beep per second).
  • The motor rotates the drum in clockwise
  • All buttons are inhibited, as long as the machine is in the Error
  • All LED's flash until the Program Selector is moved (the door can be opened).

Every time the Dryer is found in Error Phase, it must be powered OFF and restarted. If the Error Phase persists, then launch the AUTO-TEST to be informed about the Error Number.

Thermal Fuse Intervention E 8 The control has to detect N as a heater feedback. If L is detected for more than 20 minutes, it means the thermal fuse is open. Rear temperature is grown over the thermal fuse threshold (206° C)

Non Blocking Error, Dryer makes a Cool Down sequence and displays the error condition with 1 Hz LEDs

blinking. Display shows “E 8”.

Change the thermal fuse and check mechanical circuit (something occludes the

circuit), check the Wiring.

Thermal Cut-Out Alarm (automatic reset). E 9

Control has to detect N as a heater feedback. If it detects L and then N within 20 sec., this means there was a TOC

intervention.

The Thermal Cut-Out switched off the heater, due to a temporary overheating. The Error is not displayed, but only saved in Data Flash. The Dryer switches to Reduced Power. Check the conditions of the Heater and of the related wiring, the filter cleanliness and the installation.
Missing Load E 10 During the Heat Stroke Phase (automatic cycles) the temperature increases over 80° C. The Dryer is working empty, without any laundry load.

The Error is not displayed, but only saved in Data Flash. The cycle goes on with a Cool Down sequence and is

ended.

Correctly load the Dryer.
Rear NTC Error (only Condenser Dryers) E 14

The Rear NTC is short circuited or open circuited, or has an incorrect resistive value (out of the range - 14° C – 95° C) for

more than 15 sec.

Rear NTC not connected or damaged.

Drying Cycle is halted. All LEDs blink together (generic error condition).

The Display shows “E 14”

Check Rear NTC and the related Wiring Harness.
Heater Relay glued contacts (Front Thermal Fuse for Vented machine) E 15 When the Heater relay is opened, the control must detect L through heater feedback. If it detects N for more than 8 sec., relay is glued.

The heater relay could have glued contacts or, if the machine Vented the Front Thermal Fuse is

opened.

Drying Cycle is halted. All LEDs blink together (generic error condition).

The Display shows “E 15”.

Replace the Power Card.

One Response to “Hoover Tumble dryer VHC680C-80 Dryer stops and lights to flash what error code is this”

  1. Mark Daniel says : Reply

    Hi Paul, I have a Hoover VHC 680C 80 which has been fine for years, only needing a replacement heater a few years ago.
    However, it has now decided to completely stop, no power anywhere, no lights on at all.

    I’ve checked the usual fuses etc and power should be getting in, but it’s not showing itself. Any ideas?

    Thanks,
    Mark
