I think you mean a dh error code which is a defrost problem either your sensor or heater is bad

Its is a load cell error.

This could be a power issue. Make sure your battery pack wire connections are good. If they are loose, I suggest purchasing the Seca 400 power adapter, which works with this model.

This is an EEProm error. Recalibrate the scale or write the correct EEProm data by service program

I do not know this particular scale, but you might try this solution that works with many electronic scales. To activate the scale, lightly tap the scale, placing enough weight on the scale to initiate the electronic process. (A foot tap will do.) Wait for the display to show 0000 (or whatever the ready state display of your unit is), and THEN step on the scale.

We don't understand what you exactly mean. If it means a eror code, please find below the error codes and its solutions.
Er FS - Freezer Sensor Error
Er rS - Refrigerator Sensor Error
Er ds - Defrost Sensor Error
Er dH - Defrost Heater Error
Er CF - Cooling Motor Error
Er CO - Communications Error Er-Ff- Freezer fan fault. Write again if you're not satisfied with this answer.Thanks.

Sounds like it wasn't initialized, even though it says Er 4 instead of Er 0... According to my manual, to (re)initialize it and reset it to zero, tap the platform lightly. It should show zeroes running across the display for a second or two, then show all zeroes and turn off. It should be re-initialized...

Error Codes for the 5757 (according to my manual):

Er 0 Initialization error (remedy described above)

Er 1 Instability error (step off the scale, then back on)

Er 2 Overload warning (registering weight beyond the 440 pound max)

Er 3 Contact error (body impedance beyond technical limit - try dampening feet and try again for better contact)

Er 4 Bodyfat error (bodyfat percentage is beyond range - try dampening feet and try again for better contact)

Er 5 Bodywater error (bodywater percentage is beyond range - try dampening feet and try again for better contact)

here is the owner manual from taylor http://personalcare.owneriq.net/mdownloads/500eae21-4ecd-4504-9c69-a27dc677644a.pdf

er ff means that the control board is not sensing evap fan motor operation this means either a bad fan motor ice in the fan motor or bad control board. you can verify fan operation by opening freezer door and feeling for old air blowing from back of freezer compartment. you will have to push in the light switch to get fan operation.
for corndo that has same problem you actually have a different problem. er dh means the control board is not sensing defrost heater operation. the most common culprit is a bad defrost sensor. message me back if you need instructions for trouble shooting..thx peyton
