Check the filter and at the bottom of the unit. Glass shards can get into the pump and cause serious damage and even water leaks. Cutlery can extent through the hole and inhibit the spray arm from turning, causing poor washability. When the technician arrives and the load has been removed, the problem cause may not be apparent. Any water leakage should be looked into immediately.
Water can get into motors causing major damage, or cause flooring to rot.
