E70 fault flashing on screen - Olivetti JP 192 InkJet Printer

Vizio circuit is very confused, as they have no service manuals of their own. you cannot get any details about it, or any service help. Your son, whatever he may be, cannot set it right because, there is no details about it. Please forgive me. I did expressed my service experience, with 46 years. OK? If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

E70 indicates a fault in the heating circuit

Family error code E50 means a problem with the washing motor. Family error code E70 means a problem with the NTC sensor. In my experience, E50 is most common fault in worn carbon brushes. But in any case family error code E50 is shown to the customer. In service mode could be: E51,52,53 and 54. The same applies to family E70 error code that will be displayed in service mode as error code E71 or E74.
E50 error code could be: motor winding, power board, tachymetric generator, motor relay on power board, wiring between motor and power board and wiring between tachymetric generator and electronic.
E70 error code could be: faulty NTC sensor, wrong position of NTC sensor or to much limescale on it and finaly wiring between NTC and electronic.

Good Morning Jazy, this is JK. I see that you are receiving an error message E70. The E70 error means that the Main Control Board is not seeing the correct water supply. I would suggest swapping the hot and cold hoses. Hope this helps!

You could trace the heater circuit from the controller unit please check this link for tips to open the unit.
open control panel

Check heater element

I Have AEG Lavamat 76810 E70 7 Beeps and Beeps never stops

The water was not hot
I took all the multi-plugs out and put them back in the whole machine ALL CONNECTORS
Now it works fine E70 is gone

HI, this is a major control board fault code. the chip set on this board is damaged. it cannot be repair and, it is recommended to replace the entire control board(main) in this case.

A service call is recommended.

viewsonic monitors are good for about five years then they are a fire hazard

Hello,

I had this exact same problem with my Frigidaire washer (E70) as bubbles100. I called an appliance repairman on 5/14/09 and paid him $60 to tell me my hot and cold water hoses were reversed/not properly installed.

This repairman was the cheapest priced $60 and he would work till he found the problem. I had one appliance repair company wanting to charge me $90 for 30 min and another wanting to charge $120 for 30 min. Hopefully this information can help save the next person some money by trying this first.

Check your outlet filters, clean out. The machine will not spin if the filter is blocked. Also check your inlet into the machine. Clean screens on both ends of the pipes. Refit carefully.
