this warranty must be obtained by the following

GENERAL 

Since it is the responsibility of the consumer-owner 
to establish the warranty period by verifying the 

original purchase date, 

Meridian

 

Appliances recommends that a bill of sale, delivery 

slip or some other appropriate payment record be 

kept for that purpose. This warranty gives you 

specific legal rights, and you may also have other 
rights which vary from state to state. 

 

EXCLUSIONS 

In no event shall 

Meridian

 Appliances be 

liable for incidental or consequential damages or for 

damages resulting from external causes such as abuse, 

misuse, incorrect voltage or acts of God. 
 

This

 

warranty does not cover service calls which 

do not involve defective workmanship or 

materials covered by this warranty. Accordingly, 

diagnosis and repair costs for a service call 
which does not involve defective workmanship 

or materials will be the responsibility of the 

consumer-owner. 

 

In addition, the following work is not covered under 

warranty and does not constitute warranty work: 
 

•  Installation - improper hook-up or leveling 

•  Maintenance - cleaning of air and/or water filter. 

•  Damage - replacing broken door handle Most work is 

covered. The defining factor is, has the machine 

malfunctioned (

Meridian

 is responsible) or has the 

customer omitted or done something to cause 

machine to malfunction (customer is responsible.) 

 

Some states do not allow the exclusion or limitation of 

incidental or consequential damages, so the above 

limitation or exclusion may not apply to you. 

 

Please Note : The warranty service for 

Meridian

 

units is provided by Appliance Desk and hence for 

service on any 

Meridian

 units please contact 

Appliance Desk.
