I have zanussi ZWH 6140 P WATER WONT DRAIN ERROR CODE 5 FLASHING RED LED LIGHTS?


First, always check carbon brushes on main motor especially if the appliance is in use for several years.

Five times the red alarm means a problem with the engine washing.
So, could be:

E51 - Motor power triac short-circuited.
Current leakage from motor or from wiring; Main PCB faulty
E52 - No signal from motor tachometric generator.
Wiring faulty; Motor faulty; Main circuit board faulty.
E53 - Motor triac sensing circuit faulty (wrong input voltage to
microprocessor). Main circuit board faulty.
E54 - Motor relay contacts sticking (high voltage level when
the relay switches to OFF).
Current leakage from motor or from wiring; Main PCB faulty;

Rapid reading last alarms:
Press the START/PAUSE button and the nearest option button simultaneously (4 and 6) for at least 2 seconds: the LEDs initially switch off, and then display the flashing sequence indicating the last alarm.

Poineer deck amplifier dc-z74 relays click but set deck does not come on no display lights dead unit


Part of your PowerSupply is Frito.
Probably the +/- 15 volt rails, could be other.
Check inside power voltages, probably some regulators are gone.
Preferably get a tech unless you have the know-how and test equipment...

F-08 indicated.


Indesit or Hotpoint washing machine flashing 8 times or displaying error code F08 usually indicate "Heater relay can't be activated" or "heater relay stuck".
The heater relay on these machines (as at time of writing) is on the pcb, the main control board at the back of the machine. Sometimes they can get jammed, and freed with a gentle tap. Other causes of this fault listed are "check pressure switch, heater & module connections". Therefore this isn't an easy diy fix and if you don't know what a relay is or looks like it's best to get in an engineer for this fault.

Some descriptions on various models also still say "heater relay", or "heater relay can't be activated", or "heater relay stuck", but also add, "check pressure switch connections for heater, wiring and module connections".

Hi, Rx-v559 power button doesnt power up amp. +5v stb is active... whats the most likely problem?


If the power relay clicks. It may need the main power transformer. Primary of the transformer should be almost a short, if it is open-it's bad.
If no relay click. It could be main micro, stand by relay or the transistor that switches the relay on.

It might be the relay itself, you sound tech savy have you tried testing the transformer and various other main board componets?

LED Indicator Problems & Flasher Relay?


Modern Ducatis (and cars) don't have a conventional flasher. The blink rate is controlled by the dash cpu. The blink rate change is used to indicate that a bulb is out (by sensing low resistance). Using a resistor will fool the cpu into blinking correctly.
