What happened? 

In case the printer detects a problem with the modular bed, the display will show the following message: "Heatbed tile no. #: Damaged tile or wiring. Follow online guide to diagnose".

Error name: MB heater disconnected

Error code: #17250

The error message includes the number of the affected heatbed tile. The error might indicate an issue with the cable connecting the indicated heatbed tile with the modular bed electronics, or with the heatbed tile itself. 

How to fix it? 

A visual inspection

Check that the indicated heatbed cable is correctly connected with the modular bed electronics, and with the heatbed tile, and reseat the connection. 

Check the heatbed tile for physical damage, for example, a scratch on any heatbed tile surface, or a cable in bad status on the bottom of a heatbed tile. 

Swap the cables

Swap the heatbed tile connection indicated on the error with another heatbed tile connector, and check if the indicated heatbed tile number in the error changes, or remains the same after the swap. 

If the error changes to another heatbed tile number after the cables swap, then the cable is causing the error.
