A control system for handling a clogging condition in a dishwasher, the control system comprising a data processing device and a memory having a computer program stored thereon, the computer program comprising program code which, when executed by the data processing device, causes the data processing device to perform the steps of:

• detecting the clogging condition;
• upon detecting the clogging condition, interrupting a wash cycle of the dishwasher and executing a remedial operation to remove the clogging condition;
• wherein the remedial operation comprises:
• executing a drain operation for a predetermined drain time during which a drain pump is continuously or intermittently operated to drain water from a sump of the dishwasher;
• following the drain operation, executing a fill operation for a predetermined fill time during which a fill valve is continuously or intermittently activated to add water to the dishwasher;
• following the fill operation, executing a circulation operation during which a circulation pump is continuously or intermittently operated to remove the clogging condition;
• determining if the current position of the wash cycle is a predefined allowed position upon detection of the clogging condition;
• and
• interrupting the wash cycle and executing the remedial operation if the current position of the wash cycle is a predefined allowed position.
