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.

How to fix your gas furnice


most gas furneses have a red light on circuit board wich is located on intake. turn heater off then have someone turn it back on while you watch the circuit board. count the # of times the red light flashes before it pauses. it will flash in a cycle. for instance it flashe 3 times then pauses for 5 secounds then flashes 3 times again on and on. look on the back of the panel cover,their will be a diagram, in the diagram their will be dianostic report that will include what that # of flashing red light and what it means. for examle 3 flashing red lights ps stuck open. that means pressure switch stuck open. replace the part and your back up and running.

Why wont my tv turn on? a red light just flashes


Right now, your TV is in " Protection Mode". A damaged part has occurred inside on one of the power supply boards. The red flashing light is a trouble code for a tech to trace the trouble circuit path.

If you have electronic experience with circuit boards, you can find a Service Manual for the TV on the internet for less than $20. This Service manual will have the schematics, red light codes, circuit diagram, and part number list you need to fix the board.

Some el.components are loose on tv circuit board.I have removed the back cover,supported tv picture tube 45 deg.against wall.This tv is heavy!One screw on left holds the circuit board to bottom case.Removed and supported this board on few heavy books.Turned tv on and gently probed all the componets on top of the board with plastic drinking straw.In my case transistors Q-830 and Q-421 needed resolder loose joints.These components are mounted on flat aluminium heat sink strips located sligtly left of center of the circuit board.Also blobed bit of silicone into base hole and foot of alu.heat sink to support it.

I have the same problem. It seems that the group motor issues. I ve opened up and found the group motor is coming some sparks. I know very well Saeco Magic Cappucino , Saeco range is more or less the same, Saeco incanto, first time deal with it , somebody just brought it to me to check it. I might fix it if find parts for it.
Load circuit means a lot, flow meter, pomps, could be the electronc board, bewing unit blocked up with coffee, so basically there is no water in circuit water or is air in water circuit....You have to check everything,

Tv Problem


Sony TVs generate an error code. The front panel LED (red) will flash anywhere from one to eight times which can isolate the problem circuit. It is not always accurate.

If you have a test meter which can read DC voltages and resistance in ohms, you can locate the problem area. If you lack the expertice to do so, contact a sony authorized servicer. If you have the ability, start by checking fuses on the "G" board ( power supply board) and the "D" board or deflection board.

A major problem area in this TV is the convergence circuit. There are six fuses around the convergence output ICs on the "D" board.

If any are open, replaces the output ICs.

Standby Red Light Flashing


six flashes corresponds to "Horizontal deflection stop". In turn the "supposed malfunction" is then either Q5013 (H OUT) is broken and/or IC507 (H Jungle) is broken.
however i would check
Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.
