    This IS the unit we have and model numbers match along with picture of it. We get an error which reads E4. The manual does not address and E4. Only 4 other E's.
    This same question was asked in comments at another "manu​als" site but was not answered.
    ​What is an E4 and why is it not in the manual if the machine says it?
