Unblock your drain pipe to allow the water and food particals to flush properly.
Always run heaps of water through the waste when you use a wastemaster as it helps to ensure all the food particals are flushed down the drainpipe to the teminal and do not dry and stick in the waste pipe resulting in exactly what you have there now – a partically blocked drain waste pipe.
