March 31, 20215 yr Morning All, Hope you are well? We busy with an installation of 2 thermosyphen systems, each on opposite sides of a building. The first one is working perfect, Geyserwise Max working spot on. Second system, Geyserwise Max is throwing out and error "EA" "E7" - communication error. Ive tried an alternate display unit and swapped out the display plug on the control box with a alternate one. Have I missed something or is this error 7 not only related to the communication between the 2?
March 31, 20215 yr If you reset the Geyserwise. Swith of the power supply to the geyser. Then also disconnect the battery or solar panel so that there is no power supply 12v and 220 v and then restart.
June 11, 20215 yr Hi, I am experiencing exactly the same problem - alternate "EA" and "E7" error codes. I have checked my sensor inputs, unclipped and reconnected all the display cable connectors. No luck. Phoned Geyserwise this afternoon to get tech support. Left a message for a techie to call me. 2 hours later still no call. Need to speak to the programmers - they are the ones who will provide the best answer. Russell
June 14, 20215 yr Further to my initial post, the Geyserwise tech chappie did call me. Apparently the alternating EA and E7 means software corruption. They can try fix it, but generally a new controller is indicated. Seems like a hardware upgrade to CMOS of something similar could solve what seems to be an increasing problem. Apparently the surges resulting from Eskoms load shedding are not good for the board. So I went to Centurion today and the guy who helped me said E7 is the problem indicator. Turned out I needed a new controller. Surprise. After installation, system still not working. Now getting E3 which is geyser sensor not found/working. I have checked it all the way back to the control unit. I get just over 4kOhm which seems in range for the sensor. If I swop the two sensors around (solar panel temp & geyser) I confirm that the input to the controller is working. I'm stumped and would appreciate ideas.
August 13, 20223 yr Good day. I am experiencing the same problem. I even swopped the controller and the main board but stil giving me the same "EA" error. Not even the led on the board comes on like on other perfectly working systems. Something must be wrong on their boards/controllers. We can't all experience the same problem.
August 15, 20223 yr Our conroller is dead, no power, it just died. We need technical support, Cape Town area.
October 22, 20223 yr HI, can someone help with the EA and E7 error code. Just started having the problem. Pls advise the best way to fix this.
February 4, 20242 yr 15 hours ago, CocoPops said: Hey, just started getting this, any definitive fixes? Normally E7 error us a break in comms to the TSE unit. Check each of the wires at their connection or for continuity. Just a basic suggestion.
April 16, 20242 yr Hi all So i had alternating EA and E7 codes and managed to clear them, here's what i did: Step 1: switch off power for 10 seconds Step 2: switch power back on, flashing codes stopped left with solid EA Step 3: found damaged wire between display and controller, as well as sensor cable, (fixed these wires) step 4: switch power off again for 10 seconds step 5: switch power back on, all faults cleared and working normally Hopefully this helps
